That minefield you mentioned has bombs that were laid over the course of 300+ years.
A lot of people think that we live in a "PC culture" and lament that things that used to be okay to say are now verboten. What amazes me about this line of thinking is that the things that are "now" deemed objectionable have always been objectionable to the people complaining about them. There are places in this country where a black man could have lost his life if he suggested that something a white man found funny was inappropriate and shouldn't be repeated.
For example: "Why is it all of a sudden offensive to tell a black guy 'you're out of your cotton picking mind? I said it all of the time when I was a kid." I can't speak for white people, but that phrase is and has always been ignorant, disrespectful and dismissive of the connotations made when describing cotton picking.
The thing is, I don't think most black people have hissy fits over people saying things like that but they do have them when someone is told that the phrase is offensive and the response is basically "tough **** if you don't like how I talk". Communication breaks down. Whether you think somebody is making too much of it is not the point. It's not about you, so why not try to show respect? If you can't, don't gripe when you get disrespect in return.
And I'm hearing guys who are mad at #MeToo. They say that they can't compliment a woman at work about her perfume or her dress anymore. If your idea of a "compliment" is to tell her that you wish your girlfriend's dress/cologne got you as hot as her's, then it's out of bounds. I spent years explaining where the line is and still had to conduct investigations over idiots who couldn't find something better to do than to talk dirty to women at work. Here's a hint: If you think that she looks so good that you need to stare, be an adult and look at something else anyway. And keep your opinions to yourself.
