It could have been that parent graciously took my suggestion and replaced "old guy" with "technophobe" in his/her comment, while mine stayed, implicitly making my comment a rather incorrect interpretation and triggering down votes from others. Downvotes are a small price to pay for clarity :-)
I believe he's being downvoted because some believe that there should be a balance between political correctness and skin thickness rather than just full on PC. (This includes me.)
It's a lot easier to have a thick skin when you're in a demographic nobody discriminates against.
I'm sure it is. I'm not trying to minimize discrimination.
Well, you did talk about "balance" so you are to some extent.
[Edit] Also, you called it "PC" so, yes you are minimizing it.
How dare I?
Well, you do you.
There is no such thing. Every demographic gets discriminated against in some way or another, in ways that are not always directly comparable. Self-victimization, I'm sure, will be of great help.
