Sounds like you have it made with most not being involved or active.

Since you're not baptized & not active, why make a big deal about it? You will put them all in a tough position & divide the family.

Telling them why you disagree with the religion will instantly make you an 'apostate' to them, which makes you SUPER involved & active against them.

Maintaining a neutral position may be a good option for you (not openly against, but indifferent). The same as most people with family & friends in standard religions.

Also, just guy to guy, dont do a ppt. Its painfully awkward & dramatic. If someone tried that, even if I agreed with the, Id have to kick them in the balls for being a ridiculous person.

Good luck.
