Someone Role Playing an idiot is just as rude and annoying as an actual idiot.
In fact it might even be worse because they should know better.
This style of "debating" on the internet where people just repeat what they imagine the "other side" think but with implied sarcasm is incredibly unhelpful. It does nothing to further the conversation and exists only for everyone to set out their stall on their position.
I fully understand your point. I didn't find the comment rude or annoying personally. But there is a reality in that comment - my own brother pretty much echoed those words, calling me out for asking him to look at the data. Got pretty angry actually and called climate change "a carbon tax scam" and dismissed me as a fool and rational science as fake. I was genuinely shaken by that as it's not an anonymous internet comments spat, but your own flesh and blood - up close and personal.
