A lot of forums have an 'Introductions' board, maybe something like that labelled New members or summat, ease them in slowly.
I worked in the motor trade for years so it takes a lot to offend me but we all have 'off' days when we take things more seriously than we should.
I think biking in genral has moved on like everything else, there is a more diverse group of people riding bikes now and you can either embrace that, as most of them do love bikes, or you can sit in a cave and hit yerself on the head with a club.
I ride a bike for more than one reason, I don't go to meets but I wouldn't rule it out. I joined this forum to get lots of info on my Blackbird and chat to other people who like this particular bike. I would say this reason for joining is true for 99% of the people who join so they should be recognised for at least having some taste. :yo:
