Ha'aretz allows antisemitic comments on its Facebook page

For the past nine days, on Ha'aretz' Facebook page, you can see comments like:

I recall 100 million Christians being killed last century by Jewish Bolshiveks

Maybe you also forgot about the Armenian Holocaust in 1915? The event the coined the term "genocide" The 1.5 million who were slaughtered by the "Young Turks" who in fact were all Crypto-Donmeh Jews.

Heil Hitler, I wish he was still around! At least Israel would have not existed.

Granted, there are many idiots on Facebook, from all sides, and it is hard to police every comment.

But a year ago, Haaretz slammed Binyamin Netanyahu for allowing racist comments on his Facebook page in the hours after he expressed his condolences for a horrific crash that killed ten Arabs. And they also condemned Walla for allowing similarly disgusting comments.

Netanyahu expressed sorrow over the accident, but his aides did not remove the racist comments from his Facebook page or denounce them.

Eventually, the comments were removed from Netanyahu's page.

So why exactly are hate statements considered unacceptable by Ha'aretz for some online forums - but perfectly OK on Ha'aretz' own page? Is Ha'aretz  not obligated to remove or denounce hate statements on its own forums?

Or is Ha'aretz-style morality only applicable to people it doesn't like?
