People used to hang out because you literally had to leave the house back in the day. Now people have more options. More options means people aren't going to just force themselves to be around people they don't like.
And it needs to be said that alot of people don't know how obnoxious they really are. Especially people that only communicate through arguing, yelling, and debating. I know people that think every conversation is supposed to be adversarial or like a competition.
For years, a lot of the extroverts and super outgoing people abused the fact that people basically HAD to be around them because there was no internet or streaming or online gaming etc...
TLDR: a lot of people lack self awareness and don't really know annoying they really are and blame it out social media fukking up socializing. People just have more options now than going to a bar or club to stand around.
To add to this every group had that one person who was the super annoying one but he was apart of the group and that’s the way it was but now you can filter out those people or just flat out ignore them so those outliers get left by the wayside.
