You don't have to. But at least be consistent in your reasoning processes. Do you FAIL to engage in discussion on liberal-dominate sites because your arguments are weak and based on emotion? Then why do you come to that conclusion about others?
I do not purposely seek out sites that lean one way or another politically. I seek out sites in which I have an interest in the subject matter. Flying, the outdoors, shooting sports, bicycling, etc. That being said, I do occasionally post and debate on our local newspaper's website, which is very, very liberal/progressive, and do debate folks there, and I am certainly in the minority. They typically run 2 - 4 anti Trump articles per day, which never seem to be based on fact5s, but conjecture. Often they are Washpo, or AP re-prints.
Don't have time for that, sorry. It's a loaded question, anyway, and it appears you've already made up your mind.
OK, no problem. Yes, I do believe many policies enacted, and promoted by liberal/progressives are both based on emotion, and often designed by their leadership to gain power, budgets, and grow government. The "do gooders" get deceived by these power/money hungry Dems, sometimes community organizer types, into thinking more taxes, and more government will actually help the situation.
