There is no need to relate to people in your social life that you are a Satanist.
If word gets out people may look at you funny, judge you, get xtains to 'pray' for you,
or potentially could even be in danger. In this place and time it is not yet safe.
Satan has said in the Al Jilwah,
"Do not mention my name nor my attributes, lest ye regret it; for ye do not know what those who
are without may do."
If you have close friends who you know are open minded and trusted enough you can talk to them
about paganism, occultism and so on. And you can of course try to deprogram people in your life
and society at large from the lies of christianity and communism with facts and statistics that sort of thing.
I assume this is what you meant when you said relate to people?
In regards to the other question its normal to want status, to be liked and popular, but likes on social media are mostly superficial. You are of course free to use social media but I really wouldn't worry about it that much.
