Be more charitable in your reading of others' comments. Even if you could take them to be presumptuous or rude, responding as though they are more nuanced will lead to a better experience for everyone.
Here, it's entirely plausible (and frankly likely, given how easy it is to come up with a dismissive answer like yours) that the author meant something like "those who are inspired by cuisines that traditionally use a lot of peppers, like Mexican cuisine, seem not to understand the reason they're used in those cuisines."
It's entirely possible that the other person has the opinion you read into the post. It's possible that they don't. Nuance is easily lost online.
I'm not trying to offend, just to be clear and to clarify the other person's position in the process.
I am not angry at the poster, but I sincerely think that the first dismissive statement here was the one I replied to. It shuts discussion down before it gets to happen.
As someone who enjoys spicy food (and used to eat super spicy food), I have been confronted with this argument often. If you put yourself in my shoes for a second: it is pretty insulting -- here's something you care and are excited about. And there's someone who doesn't understand, and claims you're missing 'the point'. I think it's valuable for a discussion to point this out in no uncertain terms.
Edit: thank you for the feedback though! Next time, I'd probably say the same thing with a bit of extra sugar coating.
