I think there is a lot of truth in what you suppose, and yes some older members can be very rude. Maybe they think successful Forex traders need to be ruthless with their plans, so are just warning people to be tough.
A couple of years ago shortly after I rejoined Babypips, I wondered if the forum was the sort of place to learn in small teams. I have seen no evidence of that but I may be mistaken.
I did a local internet search for “forex investors in Manchester” - close to where I live. To my amazement I found a Forex trading club with about 900 members. I attended 3 of their meetings, which were suspended unfortunately, when Covid 19 first hit. I keep in touch with some of the members via SMS messages, and the founder said he would likely reinstate the meetings. I will go along again if he does. The meetings were typically held once per month, attended by between 30 and 60 people, and attendees either went home or retired to a local pub for meet and greet. We tend to think that we know nobody with similar interests locally but depending on where you live you may be surprised. Try a google search naming your nearest town or city.
