The right has a bigger problem with misogyny and anti-Semitism/racism if you look at the big picture. Stella Creasy doesn't get sh1t because she is a woman, although some tw@ts who insult her are misogynist. She gets sh1t from some on the left because she is perceived as a phoney who actively dislikes those who support Corbyn. Why don't people call the right-wingers who abuse and threaten Diane Abbot (by far the most abused and threatened MP) "misogynist" ? It's because they would tell you that the abuse they give her isn't to do with her gender. They also say it isn't to do with her race. But it's not members of Momentum/the left insulting her, so the media don't report it as a racist or misogynist problem of the right, not in the same way as they do if insults and abuse come from the left. And I actually agree to a degree, I think those who want to give Diane Abbot sh1t for her politics aren't necessarily motivated by her race or gender (although some of them are).
It wasn't a member of the left who went out and murdered a female MP, that was the work of a far-right neo-Nazi. Right-wing ideology, stirred up by poisonous rags like The Sun and The Daily Mail contributes to the climate of hate that would make an MP the target of a crazy person to murder -- but how is that reported on in comparison to any wrong-doing by those on the left? The guy running over Muslims in his van also wanted to kill Jeremy Corbyn. Consider that there are far more left-wing activists than right-wing ones, how many people are being murdered by the left in this country? And how many by the right? The far-right are allowed by the media to be detached from the right in general because it suits them to do so. Another example, how many Labour MPs are casually using the word 'N1gger' in political meetings? The Tories have that in their recent history, yet they don't have to own that in a way that the media would say "The Tories have a problem with black people." It was just attributed to a lone MP and left at that. Now imagine a Labour MP is on tape using equivalent words about Jewish people. That would not be reported as a lone MP with a problem, it would be reported as the left and Labour having a problem with anti-Semitism.
And just an FYI -- the head of Momentum, the founder, is Jon Lansman, now on Labour's NEC. He is Jewish. Apparently he has overseen the formation and organisation of an anti-Semitic menace. You know, it is possible for a Jewish MP or a female MP to be given sh1t about their politics and that abuse not to be motivated by race or gender. That's not to say that it doesn't exist at all, there are anti-Semites on the left, there is misogyny as well. But this exists to a much larger degree on the right, and like I said, the abuse of female MPs or MPs of ethnic minorities by those on the right is not reported on in a way that smears the right in general as misogynist or racist.
