A lot of the most preoccupied are TERFs who embody the most insulting stereotypes of womankind.
The constant obsessive hatred is a cope for how impotent and incapable they are. They'll just exist and whine and act like self absorbed infants who not only do nothing of consequence to take charge of the situation, but who actively attack/hinder the people who'd try to help them since people who are more assertive and proactive make them feel insecure, and pandering to their insecurities in the short term takes precedence over everything else.
That's why they claim the trannies are such a threat to them, they're like in constant danger you guys, yet they and their buddies always make 100% sure to surround themselves with only weak men they know they can control and push around, all while they (possibly even more viciously than with men) try to rip down women who are more confident and successful than them, especially if they have a happy family with a husband they respect.
For everyone else it's mostly because trannies are clowns who are very easy to get a reaction out of and will have a break down if exposed to any kind of criticism.
