There's a difference between pointing out that not every claim needs to be pointlessly supported by evidence and posting an image of a pig shitting on its balls. You might think it insulting for me to say I don't need to back every single small thing up and that you can find it yourself, but it isn't an insult. I'm not calling you names or anything.

Sure, getting annoyed is expected. I don't expect anyone to be on perfect behavior all the time. I do think it's good to not engage if you're only adding an insult rather than a contribution.
