This is very familiar to me. There are things nobody talks much about because they are obvious and everybody knows them already. There are also things that nobody talks about because everyone is lying to themselves about it and actually believe are not true (though some part of their brain unconsciously knows it). If you aren't one for the lies, you can mistake one of the latter for the former, and you will think that you are just stating the obvious, but really you just stepped on a landmine. Has happened to me many times.
