I've heard that a key feature of the troll is leaving forever after a few deliberately inflammatory posts. Mere disagreement (even very strong and angry disagreement) isn't trollish. So. No. There are people who will call you a troll if you strongly disagree with them. But that doesn't make it so.
I've also heard that a true troll will post something that is not merely inflammatory but designed to get a rise out of the maximum number of people on the board and against the general spirit of the board. If somebody came onto WP with a post about how all Aspies were horrible people who deserved to be bullied and then disappeared after a couple replies to the (inevitable) outrage, that would be trollish. It's inflammatory, it's against the spirit of the board and it involves disappearing after posting. You have never done anything remotely like that and I can't imagine you ever will.
Go ahead and strongly disagree with other posters. That's not trolling. That's debating.
