It was more a general piece of advice. Show you are keen to be invited and it can probably be worked out. We are competent at vetting and we can spot antifa. Your approach was more 'obviously I can't come this time'. A lot of people say 'next time' and then you never hear from them again. Those who say THIS TIME are the guys who we tend to think are serious.
Telegram isn't very complicated. Work it out, we'll talk tomorrow night on there. Assuming you can get through vetting (which you will if you are genuine, and won't if you are not), we'd love to have you. We are as yet a pretty small group but we are solid. The trust level is very high and we all have each other's backs. If you were antifa it wouldn't be a safe place for you to be.
