That's a really excellent question and I've sat here way longer than I probably should have over-analysing it to try and think of an answer for you.
I do think it's possible, but it's difficult to provide you with exact steps to follow that I'd class as a catch all.
Enthusiasm is great, but try to make sure that your enthusiasm isn't riding roughshod over the context - in your example it was easy to read your enthusiasm the wrong way because it was so tangentially related to what the OP was discussing. You kind of latched on to a throw away part of the primary topic and rushed into wanting to discuss that small part of. In that context it's easy to assume you're a type of bad actor[0] rather than just enthusiastic. Make it harder for people to assume the worst by taking their conversation seriously before jumping in with your off-topic excitement.
