You're not saying what your position clearly - instead you're "just asking questions", and it's rubbing some people up the wrong way (including me, sorry). It looks like you're not apologising for that because "it wasn't your intention".

If you're sincerely trying to engage in good faith, I feel you should be apologising for your role in sending it in the wrong direction unintentionally.

To be clear, I'm not taking a position in the debate here, just commenting that the way your engaging is legitimately a bit annoying if you're not aware. The other person getting really angry isn't the best look either, but I'm sure they already know that.
