Here's the funniest part of all.

Some of the stuff we take for granted now, and which is interwoven all through our culture, will someday be deeply offensive to someone in the future...because ideas will have changed.

And we don't yet know what that stuff is. We'll never know.

So go ahead in a time machine, if you can fine one, and witness some people in the future bitching about something you don't find the least bit offensive right now. You think your behaviour right now is absolutely as it should be, don't you? ;-) God, it's a treat always holding the moral high ground, isn't it? Met anyone yet who doesn't think they are?
