This is a conversation not a pissing context or a peer reviewed study. It's very hard to quantify one's experience. I was once active on both the UK and American sphere of twitter and I feel the American side of it is much worse. It's fine to not go further and just acknowledge different people have different experiences. We don't have to go fetch studies that take ages to read fully and to critically examine just to justify every opinion we have, especially when there's probably just as many studies pointing to the opposite.
