Yes, for the most part. However there are different meanings to different people. Some mean antifa to mean being generally opposed to fascism . Others take it to mean being politically active to disrupt fascism. Others on the right use it as a made up term for a non existent terrorist group, as a means to undermine actual efforts to disrupt fascism and exert control.

If you ask most people are they against fascism and they say yes. Ask if they are a member of antifa and they say no.
