Most of them are very terse, rude/dismissive, and in my view fall on the wrong side of hackernews etiquette. eg, "Sure you can. Just X" is not a educational or persuasive construction and neither are several other comments you've made on this submission.
If nothing else, I'd encourage you to respond to the best version (steelman) of these critiques, which will improve the quality of discussion and be more persuasive.
