If you don't like what you hear you're allowed to change the channel... There is no reason to complain with an "I'm outraged" speech and silence a different point of view.
Yeah, there is. Postmodernism doesn't believe that real truth exists. For them, truth is just a sociological construct. Because they don't believe it's even possible to determine actual truth, they say that speech is about power, and only that.
So for them, winning the power game is the whole point. Saying nothing and changing the channel makes them the loser. Making you shut up makes them the winner (in their view).
Truth? Well most of the time people use the word "truth", I'd call it "subjective judgement".
Power? No.
Society enforces its rules. Get over it. And PC is about rules which generally enhance peace and cooperation. Being at the receiving end of a racial slur rarely puts someone in a peaceful and cooperative mood...
The "racial slur" issue was getting resolved in the '70s and was pretty much there by the end of it (this viewpoint from the hyper-Red State, culturally Southern part of SW Missouri); for some evidence, look at the dialog in 1971's Dirty Harry where a Hispanic is about to become his next doomed partner:
"Gonzales: There is one question, Inspector Callahan: Why do they call you "Dirty Harry"?
De Georgio: Ah that's one thing about our Harry, doesn't play any favorites! Harry hates everybody: Limeys, Micks, Hebes, Fat Dagos, Niggers, Honkies, Chinks, you name it.
Gonzales: How does he feel about Mexicans?
De Georgio: Ask him.
Harry Callahan: Especially Spics."
This wouldn't be funny without the taboo that was strengthening at the time.
No, today's PC has nothing to do with anything "peaceful and cooperative", not when it consigns to perdition all of us white heteronormatives in fly-over country, probably more than half the country. It has no limiting principle, is frankly totalitarian, and the end game is going to be arbitrarily ugly.
So you are reserving your right to hate certain people without being called someone who hates ceartain people, and if these certain people objects and hates you back, it's because you country is totalitarian?
It's objectively clear a large fraction of this nation hates me and mine. They're quite clear about that, and have no shyness in expressing it, and a bit too frequently express where they want us to end up (see below, hate is unwise).
I, at least, don't hate them in return, that's unproductive, clouds the mind, etc. Which gets in the way of many things; the more dire being effective self-defense if the current trends, e.g. social, moral, and financial, continue. Which it's hard to see how they're not going to, their being baked in the cake by now.
How does somebody saying "I'm outraged" silence your point of view? It sounds like you feel oppressed or offended by people disagreeing with your beliefs, and that by doing so, others are censoring or silencing you. If your (idiotic strawman) PC person could just change the channel, why can't you? You're not being logically consistent.
"Free speech" for a lot of people means "no dissent". I am seeing this in Germany where people think their free speech is violated, because whenever they try to put the hate on foreigners, the rest of society puts the hate on them...
All my life I thought free speech means everyone can voice his opinion, even if they are criticizing me. But obviously, this doesn't apply to criticizing people who are so obviously right. My bad...
There is every reason for society to attempt to enforce social rules. In the case of PC, those social rules revolve around avoiding offensive behavior, which is quite a good idea, once you think about it for a while...
Just imagine the worst nickname anyone ever gave you, and having it replace your real name. That's about the level of rage people can feel about "nigger", "Injun", "raghead" or whatever you might imagine.
If you are transmitting over a channel where some amount of politeness is the standard, violating this standard will and should have consequences.
So for them, winning the power game is the whole point. Saying nothing and changing the channel makes them the loser. Making you shut up makes them the winner (in their view).
