Not to mention that sometimes people take condescension as a contextual thing and not an intent or personal characteristic. So it won't matter how nice you're actually being sometimes, just dumping info on them is sometimes seen as aggressive in some way rather than excitement. 

Add in the difficulties with socializing and it can feel impossible to talk to anyone about the things that excite you.

In general people don't take their time to figure out the intentions of others. If you take your time you will see most people are not actively trying to be mean, condescending or rude, more often than not they just suck at communicating.
