I don't see the problem with being antifa. As Tony Edwards says, it's anti-facism. I'm not convinced that antifa as an organisation are being portrayed correctly in the media anyway. The largest antifa organisation I can think of was the allied alliance of WW2. I would hope most wouldn't be perceiving them negatively.
It depends — there's more than one Antifa:
- There are people who literally fought and defeated fascism — the allies in WW2.
- There are people who stand up to modern-day neo-nazis by organising counter-protests but draw the line at peaceful opposition (unless they are attacked first).
- There are LARPing kids who want to be seen as 'alternative' but would get absolutely annihilated if they actually had to fight a neo-nazi.
- There are the anti-capitalists and Marxists who have always been 'anti-fascist' and frequently stir up trouble.
- Then there are the anarchists who just want to watch the world burn — for instance, the riots in Hamburg in 2017 in protest against the G20 summit.
It's similar to BLM — there are different levels and what appears on the surface to be a sensible and noble cause is, for some, just a pretence for some dodgy ideology and an excuse to burn everything to the ground.
