What Is the Subject? 1) Milo's Behavior or 2) the Fact that the Left Is Claiming to be Fighting for Principles All the While Ignoring Any Leftist Engaged in Similar or Worse Behavior?

"Stop changing the subject" we keep hearing from people, including those on the right, who claim that we shouldn't bring up people such as Lena Dunham when we are discussing a supposedly entirely different subject, Milo Yiannopoulos. 

Isn't the point of a discussion to get to the heart of the matter and find out what the (real) subject is?

Is the subject Milo (and joining the for-once principled leftists in a sacred cause) or is the subject that the left is (once more) using the Alinsky tactics to make people on the right — and people on the right alone — live up to their principles while ignoring all people on the left acting in similar, if not worse, ways?

(See also trump's racist "Muslim ban" list that not a single lefty made a fuss over when it was established — by BHO — in 2015 or 2016;
Or Bush's "racist" behavior by not doing enough after flying down to Louisiana for the 2006 floods of hurricane Katrina; versus the crickets, ten years later, when the 2016 floods of Louisiana failed to get BHO to even leave the northeast, and that not even the White House but his vacation spot in Massachusetts;
Or the democrats' principled opposition to Flynn and every other Trump candidate versus their silence regarding BHO candidates such as tax cheats like Geithner.)

More to the point:

I thought that the election of Donald Trump was bringing an end to the right's circular firing squads.

Come on! 

Offhand, none of us is defending "the subject" of the discussion, supposedly Milo, per se; we are pointing out what the true subject of the discussion is, i.e., what leftists are up to (their usual tricks, i.e., demonizing conservatives), and asking people not to act like gullible marks.

As Ace points out, if they can do it to him, they can do it to you too. Glenn Reynolds
adds that

Lena Dunham writes a book where she reminisces about abusing her baby sister and it’s no big deal. Milo talks about being abused, says it wasn’t that bad, and Simon & Schuster cancels his contract. Double standards indeed.

Indeed, what a video of George Takei joking about child molestation surfaces, principled leftists are nowhere to be found.

Ann Althouse is prompted to say, let's look at all the pedophilia talk that public figures have survived:

Madonna jokes about asking her son (who was 14 at the time): "Do you have any friends you could introduce me to?"

 … MayBee brings up "The Vagina Monologues," and that got me looking back in my archive. I found this post from October 2006, just before the midterm election that was harshly affected by the Mark Foley scandal. David Brooks had written a column criticizing liberals for their celebration of "The Vagina Monologues," which includes one story of a woman who (like Milo Yiannopoulos) had as a young teenager been initiated into sex by an adult and who spoke of the experience in an excitedly positive tone.

 … Foley is now universally reviled. But the Ensler play, which depicts the secretary’s affair with the 13-year-old as a glorious awakening, is revered. In the original version of the play, the under-age girl declares, “I say, if it was a rape, it was a good rape, then, a rape that turned my [vagina] into a kind of heaven.” When I saw Ensler perform the play several years ago in New York, everyone roared in approval.

Echoing Ace, Sarah Hoyt points out that If They Take Milo Down, You’re Next:

if the right buys into this, denounces and piles on, it just gives power to the left.  Do you see them distancing themselves from irresponsible, economically corrupt Hillary? No.  But you self-righteous little goody two shoes can’t wait to distance yourselves from Milo.

And his is how you give the left the rope to hang you with.

Milo is taking fire, because he can communicate with college students; because he’s getting a following; because his VERY EXISTENCE denies the stereotype that the right is racist/sexist/homophobic.  The left HAS to destroy Milo.

And if you cooperate in his destruction, you are next.

You can tell them “you took that out of context, and you should be ashamed of yourself for rushing to judgement.”  You can mock them with the Shaw quote.  You can call them the judgmental prudes they are.

Or you can let Milo be taken down and cower in the dark, waiting for the knock on your door.  It WILL come.

Also check out The Dystopic who discusses three or four Alinsky tactics in his piece entitled The Media Strikes Back:

Did Milo defend pedophiles? No. Evidence exists that he did the exact opposite. He has exposed multiple pedophiles in the past, including the aforementioned Nyberg. Salon, one of the publications attacking Milo for this supposed behavior, has published many articles defending pedophilia, calling it a sexual orientation (something Milo has absolutely never done). People like Meryl Streep have given standing ovations to convicted pedophiles, like Roman Polanski. Do you really think any of this is based on principle? That the media has suddenly developed a conscience when it comes to molesting children?

They don’t care. They want Milo gone. And by extension, they want Trump gone.
