The PC concept of gender is expecting someone else to modify their views on what gender means.
I'm going to link to an article in the Daily Mail. For the record, I will be politically incorrect and state that I think Daily Mail and a few other tabloids belong to rubbish journalism.
Having said that, here's the article: Google VP told employees to stop using the word FAMILY after staff complained the term was 'offensive, homophobic and excluded unmarried people without children, animals and those with multiple trans-feminine partners'
Now, I do not know whether the article's claims are true or not but let's assume for a moment they are.
If they are true, this would be an excellent example where Political Correctness goes too far. It's even worse than what you said. It's not about changing views, it's about banning words such as 'family' because they (according to the originator) do not conform to their view of the world.
