That's an unwarranted statement. I'm just pointing out that you make comments under the guise of being "impartial" and supporting rational debate, when in reality you're clearly biased towards one political party.
Your comment was framed as "why can't people freely talk about which politician they support", which is a fairly neutral statement. But, afterwards, you proceeded to say that Trump has been beneficial for the U.S, which is a partisan statement (that most people in the U.S disagree with as per a variety of polls), and furthermore, you claimed that a vast majority of the people in the U.S would support Trump if it were not for their bias against Trump/conservatives, which is an incredibly subjective and partisan statement (and also plain wrong - because many people just dislike Trump's policies).
I mean, just look at this sentence:
>Why is it implied that the other party decides whether a position is right or wrong by simply choosing the opposite of what a politician they hate chooses?
You claim that people who don't support Trump's policies do so solely because they dislike Trump, instead of considering the fact that many people just dislike Trump's policies because they are just intrinsically bad.
