We do have some, unfortunately. Not really widespread as far as I know. I don't think I can recall any prepared physical terror action from them against the feminists in the last 5 or 10 years.
That being said theses times most prepared physical agressions I've seen that are from trans, or trans supporters against radical feminists (from throwing eggs to direct punches). Both of those may consider the other as anti-feminist, but up to now I've only see the punches go one way and not the other, so there's that to consider or not depending on your positions.
