@newstep,
I'm yakking too much, but it has been my impression - and my personal feeling - that we welcome newcomers with open arms, unless they **** up royally.
It's not a macro-"closed society'', though the micro-closed happens even to us.
Almost all people here offer 'forgiveness' of initial faux pas, hoping for people to find a basically kind, curious, and friendly method of interacting. Most members are interested in learning, and believe we can learn *something* from everyone. It is only the true horrors of humanity who seem to be here primarily to try to "shock" ( and let me tell you - it takes A LOT to shock anyone here) who get 'ignored.' A few are almost universally ignored because they harp on a very limited view and bring it to every conceivable subject - agenda-driven and relentless...
Most here are friends of freedom of speech and only consign members to silence after repeated, gross attacks on several members...in addition to the afore-mentioned bullshit behavior.
I'm not a spokesperson, but only one. Get more answers from others.
