You do realize many people don't generally read every comment in detail, especially ones they saw as right wing rethoric because of your first sentence? It's not like there is much to gain from reading such a comment properly.
Your first mistake is that the first sentence was too convincing, making any hints later that isn't a literal sarcasm indicator completely useless to a lot of people. A joke is all about the delivery, and a good comedian adjusts their delivery to their audience. By the way you react to people, I can tell you have trouble with both of those.
It is, but the same people that refuses to use the sarcasm indicator are the same ones that complains when people miss their sarcasm. I always say there is a non-zero chance people will miss the tone when reading text, so don't complain when people do when you refuse to use the sarcasm indicator. If you're gonna complain about it, it is now a your problem, as well.
You're right. I should have gone back to the original comment and read the username before replying. I'm surprised how many different people are reacting so defensively for a joke comment they didn't make.
