I think they actually do understand feminism quite well and see 3rd wave feminism for the annoying, running joke that it is. Their parental rights (men's) have been assaulted while they're told they're only good for providing financial support; when the woman decides her baby is a life; rather than a clump of cells --because, science is how you *feel*, according to 3rd wave SJW feminists.
Nobody's arguing to take women's suffrage away (unless they're simply trolling you for laughs), nobody's trying to take your property rights away; except for maybe the misogynist Islamic culture that 3rd wave feminists seem to be welcoming of --figure that one out.
3rd wave feminism is very ridiculous and only seeks to gain extra privileges for vagina while tearing down men because you think you live in an "evil patriarchy" and don't want to share the world with men; without duct taping their mouths shut and enforcing them into a life of indentured servitude. Radicals have hijacked it and turned it into a whiny subculture of lunatics who protest ...stuff...by taking their shirts off and passing out dildos. They're crazy. The battles have been won. You're done.
So, to answer your question -you "deal" with the "edgy twats" by actually being an open minded and tolerant individual as your ilk so proudly always proclaims (but typically demonstrates otherwise).
