> In the UK I'd be worried about being arbitrarily arrested, deported, and banned from re-entry.

That's not going to happen unless you commit a serious crime, in which case it's not arbitrary. I can't think of a single case that's made the news.

Meanwhile across the pond in America you have the nightly news reporting on children and people in cages screaming. People being rounded up for not being white. Little to no due process at all until you've been through 6 rounds of hell.

By "commit a serious crime" I assume you mean "publicly state that I support Palestine Action" or maybe "hold a blank sign at a protest". Those are serious crimes in the UK now. But as I said, the worst they're going to do is kick me out, not kill me, and that makes the difference.

They are currently a proscribed group, so yes, that is included in the list of things you probably shouldn't do. You're not going to get killed for it though. You're probably not even going to get arrested in most cases.

Whether or not they should be proscribed is a different issue. The best course of action is probably to wait for the courts to decide. Pressure groups damaging military assets probably aren't going to be well received by the public regardless of which cause they're for.

Small factual correction: the barrister holding the blank sign was not in fact arrested.
