First of all, you need to go do some remedial math. The percentage of DWTS watchers who are women is no predictor of what women do. This fallacy is called confusion of the inverse, and it's a probabilistic variant of the better-known converse error.
Second, even if 99% of women were to be DWTS fans, it has no bearing on anigbrowl's comment. The reason that "while your wife watches DWTS" is part of the problem (as anigbrowl identified) is that it implies that (watching DWTS) is to women as (checking out 1130 sims) is to men. It implies that in situations where men do interesting tech things, women watch TV (I assume "DWTS" is some kind of TV?). It's basically a put-down against women collectively. Note that if someone were to be putting down humanity collectively, I wouldn't complain.
Third, "politically correct" is a label principally used by reactionary dullards to dismiss arguments or objections that they see as excessively leftist. It's equivalent to calling someone a commie. Mind you, some people are communists, some people are knee-jerk excessive leftists, etc... but if that's true in a particular situation, you can just explain why it's true. Calling it "political correctness" is just a lowbrow dismissal.
That's a lot of incorrectness for one 20-word sentence.
