I am certain there was no intended malice meant in your comment Head' (or for that matter probably anyone's other responses)
But it is a tricky/sensitive subject to discuss ...And becomes even more so, when you try too hard to show, your personal non-bias.
It'very easy (imo) with the best of intention to introduce "categories & labels" into conversation, which does more harm than good.a
An example might be: "I've nothing against "gays" even many of my best friends are gay" (And the same works for any "groupings")
Another example: "Old People are cantankerous, mean-thinking, moaning auld gits, or "Old people are all loving, sweet, fun & cuddly"
