@Falco,
No need to be so mean - we are not all socially acclimated.
Back in the sixties, I ran a small laboratory, and at one point I was allowed by the department to hire help.
I picked a guy who had a lot of both cooking and laboratory experience in the army for a lot of years. He was straightforward when I interviewed him. Of all the people I interviewed, he seemed to get process.
He was also very heavy, an easy 400 pounds. He was made fun of later by another tech, another story.
I taught him what I knew at the time, and he was good, efficient, more efficient than I was (but I was better at trouble shooting), and often funny. I ended up his daughter's godmother, just as I was leaving the catholic church. I told him so, and he pleaded I do it. Sure.
He had married a woman whom he met in France when he was in the army (this was in the sixties I met him), who already had a son. A son who had sometimes been locked in a closet by her brute husband. The boy was retarded, as was said. When I met the son, he was getting along, maybe seventeen, pulling out of his very dark past. In school, hanging in.
A lot of us online have social issues, trouble dealing with others.
Making fun of people is sometimes a sign of advanced stupidity.
