Thank you, but don't mind me. I just had multiple tabs open and accidentally replied to the wrong post.

I did think the answer from jms21y in the screenshot was interesting. Years ago, before Reddit existed, I used to post on a message board where there was a great deal of diversity and still people were polite to each other - the rules were strict about that. There were also only several dozen active participants so we all knew each other. Anyway, one of the regulars was an active-duty military guy and his perspective was often very interesting. I think the ideological range of the people I talked to has become so much narrower since then. People (including me) are so much angrier now than even during the GWB presidency.
