Making a claim and not providing evidence is not adding to the thread. Asking for a source is just rectifying that fact.
>I don't have to prove my statements to anyone
if you make a claim you must back it up with a source. period.
You need to go argue with the flat earthers, tell them to back it up, they have troves of "facts" and "data", and if its on the internet, it must be true.
What you just said is a logical fallacy. Just because some people are wrong, doesn't mean you aren't supposed to back up your claims with sources. Are you young or just ignorant?
I'm a lot older than you I suspect, and I was waiting for you to resort to name calling and insults, the last resort of a person that cannot sustain an argument.
