What you would gladly take is not the standard for communications with others. You might be willing to be called every name in the book, that doesn't give you license to be rude with others.
If someone minds being called a "clown" for making a crude, loud-mouthed mistake, then that's too bad.
Abuse is not justified for misreading.
It is if the person built a cocky remark around this misreading, because that opens them up for RIDICULE, which calling someone clown is, rather than abuse.
I honestly don't care about being treated "civilly" or "with respect", but I'll point out dishonesty, wilful stupidity and disingenuous hypocrisy whenever I see it, and I'll laugh at it without a shred of phony "respect".
So please, quit preaching at me and get over it.
