I'd like to add I think it's also interesting how some people can become friends online when in fact they might annoy one another in the real world. Sometimes lack of nuance makes people react more defensively sure but I think it can go the other way too.
Even more nuanced conversations over the phone and interpersonal conversations a midst exchanging personal information, it's still hard to get a read or feel on someone especially because each person could be trying harder to project themselves in a certain way. However, hang out with someone for a day the awkwardness could come out. Therefore, I think sometimes being too restrained can be cumbersome as well. I just try to do things naturally. If I push a few buttons and rub someone the wrong way, I try not to troll or use strawman arguements (something does earn a person ridicule big time in the real world dealing with real people; nothing like trying to talk to a moron who puts words into one's mouth or recontextualizes/shifts words/topics around making them a master at BS and impossible to deal with). I try to get right to the point and stay within reason.
With that being said though, in the real world I'll generally refrain from talking to people on certain topics until getting to know them better then the degree click determines the degree interact with them (just at work, hang out on break with them often,ect.). A feeling out process I think is more warranted especially when trying to interact with one's neighbors and co-workers to keep things level and even with a degree of spacing as needed. Online can be good to be able to project an opinion and feel it out by how others respond as long as one does it within a point of reason while utilizing reason.
