I think if Tech wants fans to wear one color to games, as any AA usually does, you actively promote that color. If that message is not important, then no, I don't think it's undermining, because you've decided you really don't care. I wish it were important, but that's just like, my opinion, so your point may stand.
I'm 40 so we're in the same wheelhouse. During the time I was at Tech (and the years I should have been if not for my crash and burn lol) we never wore blue in football. From 95 until the Peach Bowl in 2008, I think we only wore blue once (2006 ACCCG - which was actually a very very sharp uni that didn't diminish white/gold branding imo). That said, anyone who says it's hard to find gold gear now should have seen the situation then. Your choices were a Russell gold Polo or a Russell gold Polo. At least until the Chan gameday cheddar came out...gross.
