Hi shakespeare, well it sounds like you're passionate about a variety of things, like to be able to influence people (positively?) in seeing "the bigger picture" in topics you care about/have a viewpoint on, hold strong values and standards, like the challenge in evidencing/justifying that you're not just opinionated at times (if that makes sense??), like stimulating arguments........
Of course some of what you actually discuss with people will sway people one way or the other in feeling strongly about you e.g. if you're arguing with me (or a lot of other people!!) subjects such as "there's no such thing as rape" then you know you are going to get some really strong feelings about you.
But otherwise, there will be people who won't like your approach but just as equally there will be people who do like even admire your conviction/passion/strength of identity and knowing who you are/what you believe in.
But it is really good that you're asking the question, it just shows that you're practicing a bit of self-reflection, you care about others, the way you make them feel and the way you're perceived. So yes, maybe depending on who you're talking to you might want/need to adapt your communication a little, just the same as anyone regardless of how "forward" they are or aren't.
So maybe look a little at things like body language, facial expressions, input from the other person, listen to what they're really saying, ask for feedback............I know you're probably doing all that anyway right, sorry!!!!
But I'd say that it's still really important not to "lose yourself", who you are for the sake of "fitting in", just to be liked by others. Your individuality matters, being able to be yourself as much as you can matters. And it's the people who value who you are who should be the most important people to you, as opposed to the one's who just want you to be "someone else".
And anyway (!!).........I'm sure there's a whole lot more to you than......."the guy in the room with strong opinions", right??!!!
