In this world of political correctness, or as it should be known, inhibiting free speech, it's important that we should speak up when we see, or hear, things that are wrong. I believe in the old saying that if you don't stand up for something, you'll fall for anything.
I recently heard someone talking about what they had done, enjoying their joke etc., which I saw as a total abuse of their power as a parent and said as much. As you can imagine, it didn't go down too well, but I stand by my position and everyone is entitled to do and think what they feel is right. I don't have to agree. There are enough sycophants in this world to blow smoke up each other's arses.
Whether that person continues to speak to me, or wants to keep my acquaintance is their choice, but I would do the same thing again because to stand by and ignore injustice and bad behaviour is wrong.
