Morality is always a tough topic, yet if people can communicate with each other in an objective, open and tolerant manner, there should be no need for any disrespect or subjective exclusiveness.
Show me two people on this earth who are identical in every single way = IMPOSSIBLE.
So, as we are all so unique and different, it is easy to fall into the trap of subjectivism, especially if we are part of a "mob" who enforce that subjectivism.
History has shown that subjectivism only brings about evil and terror, which I sincerely believe was well explained in the video.
Hopefully, nobody finds themselves as being a target as far as this post goes, my only goal here is to get us all (me first) to reflect upon ourselves, our own faults and as such our inner being.
Doesn't hurt to be self critical about things that are by all means so important in making life among humans better for one and all.
Cheers.
