I wish there were a better term for it. But "anti-charisma" is the most accurate way I can think of to express it. People naturally seem to hate me, disagree with me, etc. I seem to naturally repulse people, no matter how sociable or nice I try to be. I'm not some autistic asshole with no sense of social convention, etiquette or emotional cues, mind you. I work hard to be nice to people and follow every social norm. But if I advocate for something, no matter how careful I am not to come on too strong, it actually hurts the cause I'm advocating for. The LAST thing you want is my support.
I think there are several possibilities happening to you, probably several at once if its as bad as you report. Either: 1) you have a habit of making people feel dumb (or at least reminding them of how truly wrong they can be) or 2) you are suffering from the Double Burden at the low end of the scale for social cues or 3) you are offering your opinion too frequently given the size of the group (the larger the group, the more you have to share the "speaking stick")
Try this for awhile, don't try to persuade anyone in a specific group of anything for a predetermined period of time (you don't have to do this at work but consistently with a specific group of people). Then after a period, wait for one group decision and chime in with what you want but just say you think it will be fun or that others will enjoy it. Don't give a long winded, logically based argument, just something short and breezy. You might be surprised with the response depending on the group of people. Obviously this probably won't work with engineers but other social groups it might weirdly work.
