certain things are just so stupid that its fair to just write off what ever else they say as bullshit if someone is a flat earther their opinion is just worthless, they have no critical thinking skill and arguing with them is not going to help anyone, they are just going to feel like their ideas are worth debating the people who still say global warming and pretend that weather and climate are the same thing are in the same boat, no point trying to reason someone out of a position that they did not reason them selves in to, its best to just accept they are retarded or some kind of shill and move on, on the internet dropping a link for other people who might get fooled and calling op retarded is the best option
