"That's not my problem to fix" is a valid, if admittedly somewhat cowardly, position for normal human beings (as opposed to angry virtue signallers) to take when confronted with evil or injustice.  It doesn't matter if the human beings involved are women or men confronted with sexual assault, muslims confronted with radical Islam, white people confronting racism against people of colour, or non-Jews confronting anti-Semitism.  We cannot, all of us, all the time, be checking to ensure our opinions are both on the "correct" side of prevailing attitudes  and publicly displayed, or we would do nothing useful while exhausting ourselves in the process.  "I am more virtuous than you because I condemn X" is as useless and facile a sentiment as "I am more oppressed than you".   Sadly, both sentiments seem to be in vogue.
