Living in a reasonable inclusive place (society wise and only recently law wise), I get annoyed by all this "pride" activity since to me the fight was mostly over but then this afternoon I saw this just near the subway station nearest to me (itaewon)
I told that lady preaching on the mic that she should keep her sermons to the church but she didn't understand English and just replied "Jesus Christ". Well, that was me told. Who could argue against that? Nobody else said anything. Anyway didn't want to stir up trouble in a foreign land when I have kids to take care of.
Apparently this area houses minorities like Muslims and blacks (saw a few, was surprised and some to them as well, all friendly folks) as well as a meeting point for LGBT folks (didn't see them yet).

Apparently most of the activity happens after 1am so I'm going to miss it.
I've seen people like this a few times... not preaching on this topic, but with a microphone and speaker yelling about Jesus. I've never gone up to them and told them to shutup though 
Guess I got there too early at 8pm+. No activity.
Spoke to the local handsome young guy (I assumed) (always homme back profile photo) who spoke the best English I'd heard so far here but he was understandably more interested in getting me to buy a drink.
