Many people who post on political issues talk the way you’d never allow yourself on a Torah topic. Just saw an article in Jewish Action from someone in OU bemoaning the same thing. If you practiced to be objective and respectful to other opinions and to facts in your Torah learning, you should be able to use his skill when talking about other things. And if you can disregard facts in political discussions, there is a chance your Torah learning is also lacking.
It is also totally useless other than therapy – most of us read or heard political opinions in other media, hearing it once again on YWN will not change anyone’s opinion.
