evans,
No, you cannot expect someone to put up with your annoying BS just because you put up with their annoying BS. At least, not without getting them to agree to it. See, to them, their BS isn't annoying! Plus, you can't contract with someone for something without their knowledge or consent. That just isn't how it works. If it annoys you when your mate is not your intellectual peer, your only solution is to find someone to date who you deem intellectually worthy. Which I know does suck, because the smarter you are, the fewer potential mates on par with you there are. And if you have other criteria, as you should, the search gets challenging. But there's nothing for it, you have to accept someone's limitations or find someone else who doesn't have those limitations, those are the only options.
Also, if you want to use big words AND you want everyone to think you are smart and not showing off, you need to learn to proofread better. Typos are no big deal, but when tense and verb/subject agreement problems litter posts that are also filled with AP English vocabulary words? I tend to think the writer is trying too hard. Intelligence is reflected in effortlessness.
I have met a couple of people online who have Asperger's, and they write very similarly to you AND report similar issues with interpersonal skills and forming relationships. Have you ever been evaluated? If that is your issue, there are many resources available to help you.
