Please please give me your opinion?

I suppose it would depend on what those reasons were.If আপনি dislike someone because there black, then that's obviously a bad reason. However, sometimes আপনি just can't help it if আপনি find a particular personality annoying. I try and not use the word "hate" so much. There are only a few characters that I actually hate, and I don't hate someone (real অথবা fictional) just because they annoy me. There are a few that I just don't like though.

Sometimes (oftentimes), people feel the need to defend their পছন্দ characters from insults. I'm sure most people do this to an extent, some may just go overboard with it and start flinging insults. Generally I find it best to respectfully express my opinion in a way that doesn't get people pissed at me. For instance, saying "I don't really like x because y, but that's just my opinion, so don't take it personally." If আপনি suspect আপনি are staking your position on a controversial issue, it's usually best to try and be as diplomatic as possible.

Also, just having an opinion on an issue will make আপনি biased. It's impossible for someone to be completely without bias. আপনি just have to make sure আপনি don't let your biases মেঘ your judgement অথবা create an us vs. them mentality.

Basically, I just gave আপনি a long winded way of saying it's not necessarily wrong to dislike a character. Everyone has someone (or some type of person) they dislike. আপনি just have to make sure the reasons behind that aren't overly biased অথবা just plain bad.
