Ah.... good catch --- I have to admit I did not know what SJW meant.
That said -- when I say it's about ideology -- I am referring to extreme swings of the ideological pendulum. And I *think* that the whole PC thing mirrors those swings... and I *think* the animal farm comment a poster made awhile was very thoughtful.
Many moons ago, I had a professor in college say, "In fighting the monster we need to be careful we don't BECOME the monster".
This never left me... I think about that a LOT... because I have seen that one can be, on the surface, quite "PC", and yet, at the same time be quite morally corrupt (even by their own stated standards -- and speaking in a very universal sense, ie. not a religious one).
I have seen power shifts, and the truth is .... power corrupts.
As far as an everyday application of the idea of political correctness? My own personal rules are sort of:
1. Think before acting/speaking, but don't overthink... overthinking ends up being a very egocentric, narcissistic activity and is not good for mental health.
2. Apologize if you do #1, and it turns out you should have put more thought into what you said/did than you did.
3. Be curious about people and always be kind and want the best for another person. I moved to a very sensitive part of the country. I quickly learned words and actions that were the norm in my home culture were unacceptable to many people in this part of the country. Sometimes I understand why, but often I do not. It matters not -- if it's going to offend I will try to remember not to say/do it. Probably I won't be best-friends with these people I must censor myself with -- and that is OK. Sometimes though -- friendships grow over time despite differences in culture and people can really be themselves with each other (this is a beautiful thing), but this is earned, over time, in a friendship built on mutual respect.
4. Don't be easily offended. I do #'s 1-3, but do not always have them done unto me. It happens. It needs to be water off a duck's back..... most often, it is not worth the time and energy to "educate" someone else on how they could have treated me better. Maybe this is laziness, or whatever.... I'm just being honest. Now if it is someone else -- I have and will (pretty much a sure thing) speak up and educate. I can't stand bullies -- even if it's just out of ignorance.
But that's just me. You (whoever's reading) do you.
