Eskie...I have to admit, I'm never bothered by all the things you recounted, though I too experience them from time to time in my interactions with people.
My dealing with the same issues over and over again has to do with making the same personal mistakes, especially in romance. It equates to having stuck my hand in the fire enough time that I've finally learned and stopped it!
I did have an experience the other day which momentarily offended me. I was talking to a younger male teacher from my Related Arts team, and he simply walked away while I was in mid sentence, to go talk to a young female teacher! Yeah, I was a little hurt and offended, but then I reminded myself I have no basis for communication with this coworker and brushed it off! Later, he did come up and finished commenting on the conversation, and I thought, "Yeah, uh huh," and went on my way.
You're a sweetie. Just brush off those offensive people, I say!
