I always say whatever I believe, even if I am at work. If the company would fire me over a joke then fine I wouldn't want to work there anyway. So far I haven't met any issues on that front. Also I don't work in the US so you can't really fire someone where I live because of a joke and it's outright illegal to do it over beliefs.
I do not get the mad men reference, since I haven't seen the show. But so what if I am? No one values or respects everyone's opinions, that is just such a load of horseshit imo. Obviously people here don't value or respect my opinion for example.
> are inappropriate and have no place in modern society
This is very funny, a biological hard fact has no place in modern society? I don't even understand how this is even a controversial thing to believe yet you believe it has no place in a modern society.
I do not wish to live in your definition of a modern society.
