Replying with supposition, "I am almost 100% sure, it won't work on A320," to vendor-supplied guidance (linked image in parent to supposition) on exactly what is and isn't intended to be supported comes across as rude. It makes it seem like there is no desire to engage in a conversation, but rather just to speak one's thoughts without regard to the partner. If the first response to engage with a specific user is to critique them for the gall of calling out that they're repeating themselves, it seems rather a callous disregard for others.
