Im a member of the closest Humanists and Atheists meetup groups but no longer attend the meetings because they are predominantly retired elderly people and I find the meetings boring.

The few ideas I provided back in the beginning were ignored so I quit attending the echo chamber

No, because : I'm way outnumbered, and I strive to do good where I can. Otherwise , out living life.

Most of my off time is spent volunteering at a homeless shelter, so no time for it.
Also, I've been an atheist my whole life, I was not brought up in a religious household, so I don't really need any kind of support group.

No, I'm not. Why? Because I'm too busy living my life atm. No time.

I'm not, because I've spread my time so thin already that to seek out another group to be active in would be sadistic. As lame as it is, I'm trying to stabilize what I've got going now and hope that once my kids are older I'll still have fire in my belly.

I'm active because I want a group to exist in my area to counter the presence of religious groups. Churches, temples, synagogues, mosques, and other religious buildings are all over the place. The leaders of the groups that use these buildings are given privileges that are often not earned. I feel I can't complain unless I'm doing something about it.
