In my long and distant past, I occasionally made immature comments and jokes etc...
... but I was at times a little too childish and curious to see what offense value they may have, I literally did not know about a lot of things here and there, but it was mostly a very long time ago like 20 years and heck, as a kid, as inappropriate as it may have sometimes also been, I made other silly comments here and there. But is it OK to let it go now?
Sometimes, I was also parodying what others may have said and childishly wondered about oh what if life was like this and not like that - hell, on the last point, I STILL WONDER about it that way, as in, other than accepting reality as it is, in all its hard, tough and gritty anti-glory, and with many people just practically stating the obvious on the order of "Don't do it, its bad, simple but yet hard for many to understand due to [insert various socially critical terms here]" etc etc etc" as opposed to, say, wanting calmly, politely and intelligently to explain it all, existence of de-facto offenses and social flaws briefly, put only for the sake of argument, put aside.
Asides from that, English was not my first language, in my country Russia at the young age we were discouraged from talking about certain things in any way (heck, and even recently, in the last 8-10 years or so, however flawed and ineffective if not downright offensive in some eyes, certain as such "laws" were formed, and many public people accepted it) so I just didn't know about certain things and sometimes, I and others were too limited in knowledge or right attitudes even if deep down inside, we kind of knew what was this and that etc.
But is it OK to let it go now and also, you know, not give it anymore weight and emotional importance, thanks.
