Twitch Says “Zionist” Can Be A Punishable Slur

Now you can be accused of slurring someone by using a term they coined
to describe their own movement?

Twitch are saying you cannot “attack or demean another individual or
group of people on the basis of their background or religious belief”.

Whose fault is it, exactly, that “Zionist” has become a disreputable
term? Could it be because the whole point of Zionism is to engage in
activities that the world is increasingly recognizing as being
disreputable?
