Re: Because banning black jokes...
It's worse than that. Enforcing anti-racist values by law casts the racists themselves as victims of oppression by virtue of removing their right to express themselves. I've observed people starting to express support for racist groups in unprecedented numbers, not because they're particularly racist in themselves, but because they're sick of the political correctness lobby constantly telling them how they're allowed to think and feel about their fellow human beings. And the moment you start legislating thought processes and emotions, which is what the PC lobby want to do, you make yourselves as bad as the racists you are trying to impede.
Not only that, but in my own life I have on a number of occasions encountered discrimination on the basis of my sex and my race and there's been nothing I can do about it. Why? Because I am a member of that ultimate source of all of society's ills - the ubiquitous, overpowered, evil and perverted white male. The PC lobby isn't about equal opportunity and fair treatment for all so much as it has become about a War on White Men.
No doubt the PC zealots (the worst of whom are often themselves wealthy white men seeking to reduce the perceived competition) will get stuck into me at this point, but the facts will bear me out - the lack of any existence in Australia and elsewhere of facilities to assist white men as specifically as there are facilities to assist women, aboriginals and non-white people, is all the evidence required to establish the pervasiveness of this systematic reverse discrimination.
I am reminded of that passage in Orwell's 1984 where Winston cries, "I hate purity, I hate goodness! I don't want virtue to exist anywhere. I want everyone corrupt to the bone." This is because for him, the values of purity, goodness and virtue have been misappropriated to serve the agenda of his oppressors. Which is exactly what the PC lobby has done - they've turned the virtue of accepting people on their own merits into a weapon of hatred against white males.
I don't want to support racists, or sexists, of any stripe. I absolutely believe that freedom is founded upon treating everyone equally. I just as absolutely believe that civilisation can only achieve its full potential if every member of civilisation has the opportunity to realise their full potential. To discriminate on the basis of factors that have no bearing on ability is to waste resources, skills, and intelligence. But what the PC lobby is doing by discriminating against me on the basis of those same factors is forcing me into the same argumentative camp as those goose-stepping idiots whose wasteful, discriminatory values I equally despise, just to be able to assert my own dignity and rights as a human being.
Stop blaming white men for everything that's wrong with the world. Give us the EQUAL opportunity you give to everyone else, eliminate the evil of "affirmative action" and "hate speech" laws, and implement instead educational programs and assistance for those who are having trouble adopting the new ideals instead of merely punishing them. Then you won't be making underdogs and victims of the racists and sexists. You won't be reducing the essential values of civilised behaviour to hypocritical Orwellian false virtues. And the problems you are trying to eliminate will solve themselves by the simple nature of their inefficiency and the basic desire of every human being for freedom and self-determination.
