Reddit may actually be doing a lot of people a big favor.
Today Trump's DHS went out and arrested a Palestinian student at Columbia for participating at a protest a year prior. Our federal agents are becoming like the KGB- hunting down political dissidents.
I believe that is just a start. I think people would be wise to be careful about the things they post online. If you do post content you believe the administration may not like, I suggest making an anonymous account with an email not linked to your personal name.
I have a hunch that people will be arrested in the near future for posting things online.
i say be polite. you don't have to be super friendly or anything
being a "homewrecker" is bad, but sometimes there's more context you don't know about. i tend to give people the benefit of doubt and give them an opportunity to show who they are before I make assumptions.
i do this because in the past i have judged too quickly and been wrong about people- in both directions
