Well i answered them and gave my reasoning for why no other issue matters. If you had something to add I could explain, and its funny how so dominated by the political frame everyone is that they think this means I'm voting (for Trump presumably), which I've also never said. 

The comment was explicitly: "literally nothing about voting matters or will make a tangible difference except possibly this single issue."

then people come in acting like they are teaching me something and bring up100 irrelevant things they either heard in political ads or read in a Rothbard piece that they only first found this year.
