Seems like it.
I find Margaret Hodge's reasoning in her article (about why she called Corbyn an antisemite) wrong. People call other people Nazis - it's hyperbole - no one is seriously suggesting that there is any comparison in scale or intent to what the real Nazis did or intended to do to the Jewish people in Europe. Yes it's offensive to be called a Nazi even if you are not Jewish, but that's the point - it's supposed to be offensive as some people find the treatment of Palestinians under occupation abhorrent, and it is no less abhorrent just because the oppressor is Jewish. Yes being called a Nazi is even more offensive if you had family members killed by the real Nazis but I don't see the need to start outlawing offensive comparisons to political or historical figures on that basis.
Genghis Khan and his Mongol hordes wiped out more people than Hitler during their military expansion but maybe the autocratic brutal behaviours associated with Nazis is more widely known so the term "Nazi" is more widely used.
The Jewish community have had a lot of influence and input into the definitions of antisemitism and most of their examples that they want included have been accepted, so Margaret calling people antisemitic and trying to argue that all Jewish people's feelings have been completely ignored because a few examples of antisemitism have not been included sounds like activists trying to force people to accept their particular dogma rather than reasoned persuasion.
If some Muslim activists were arguing that it was Islamophobic to call a Muslim a "hebephile pig" for trying to marry a child, would we include that in the definition of Islamaphobia if they kicked up a big fuss, felt unwelcome and started leaving the country to live in another country where child brides were more socially acceptable?
I see no reason to support some blanket principle that the oppressed have a better understanding of reality because of the oppression they feel they have experienced as a result of their identity. If supporting oppressive policies against others who are not of your race or religion is part of your identity, then I think your identity should be open to challenge and criticism.
