Is arguing worth it? If so, when and when not? Also, how do I become less arrogant?

I’ve had several political arguments about That Which Must Not Be Named in the past few days with people of a wide variety of… strong opinions. I’m rather doubtful I’ve changed anyone’s mind about anything, but I’ve spent a lot of time trying to do so. I also seem to have offended one person I know rather severely. Also, even if I have managed to change someone’s mind about something through argument, it feels as though someone will end up having to argue with them later down the line when the next controversy happens.

It’s very discouraging to feel this way. It is frustrating when making an argument is taken as a reason for personal attack. And it’s annoying to me to feel like I’m being forced into something by the disapproval of others. I’m tempted to just retreat from democratic engagement entirely. But there are disadvantages to this, for example it makes it easier to maintain irrational beliefs if you never talk to people who disagree with you.

I think a big part of the problem is that I have an irrational alief that makes me feel like my opinions are uniquely valuable and important to share with others. I do think I’m smarter, more moderate, and more creative than most. But the feeling’s magnitude and influence over my behavior is far greater than what’s justified by the facts.

How do I destroy this feeling? Indulging it satisfies some competitive urges of mine and boosts my self-esteem. But I think it’s bad overall despite this, because it makes evaluating the social consequences of my choices more difficult. It’s like a small addiction, and I have no idea how to get over it.

Does anyone else here have an opinion on any of this? Advice from your own lives, perhaps?
