But now I try to be as open as is practically reasonable about my interests and hobbies. You'd be surprised how receptive some people can be. And those who react negatively are filtering themselves out of further interaction.
Not all people are looking for their own words echoed back to them. Like the OP who suggested this advice in the beginning, some people are really interested in seeing things from different viewpoints.
I don't know exactly why the other commenter said "you must be fun at parties," but I'd imagine it's because the parent commenter deflected from talking about things he actually wanted to talk about. Being fun doesn't have much to do with the content of what you talk about. It has more to do with you showing genuine interest and excitement for the things you do. If you don't like watching movies or playing video games, then it's very difficult to have a fun conversation about those things. CiPHPerCoder listed four things he enjoys doing over his weekends. Those topics are definitely not mainstream, but they do overlap with my interests. I would love to have a conversation about those things with him because it also adds to the variety of conversations I get to have.
Sorry, would have responded sooner but HN's rate-limits kicked in.

I do enjoy those activities, but I accepted a lot of responsibility (especially with making secure PHP code-- a feat some infosec folks claim is inherently impossible) and intend to finish what I started. That means missing out on a lot of great movies (Warcraft, Zootopia) and video games (OverWatch) that my friends are all able to enjoy.
Ultimately, I believe the work I'm doing today will make a difference tomorrow. Whether I'll be able to capture any of that value for myself remains to be seen.
