There is a lot of military check points, many undercover cops. So you need to manage your ambition about politics when you’re there. just be a tourist and you’ll be fine :)
A polite way of saying "don't be that jerk that goes to someone else's home/town/county/state/country just to tell them what they're doing wrong" which really shouldn't be that hard to do if you're distracted by all the other touristy things you should be doing.
Edit: I know this is gonna get down-voted because it's not "nice" but it's true. You shouldn't go to where someone else lives and tell them they suck or they're doing it wrong and expect to be treated nicely.
Any tourist activist is a pure idiot. People are quite capable of taking care of themselves, and if something human behaviour related looks like it needs fixing it's likely a non trivial thing to fix.
