Dear Boring,
While it's possible that you simply happen to be struggling far below your proper place, more likely is that you're failing to send the right social signals to convince people that they stand to benefit by having interesting conversations with you. The heretic of whom you think fondly, who's inept enough that you know him for a heretic, is evidently somebody who's clever around people even when that's not in his own interest.
If this proves unsolvable for you, then sure, go with the clever heretic. But if you're high enough to have inferiors, consider asking yourself whether you've visibly rewarded the first incremental moves in the direction of having interesting behaviors or thoughts around you.
There are plenty of topics on Cheliax in which I've still neglected to make people aware of my own, correct opinion. If people are only discussing topics with you on which there exists an orthodox opinion to parrot, it means they don't want to have a real conversation with you.
