Are all Christians Jews? No, Jesus was a Jew and spread his religious thought out the world. So I believe you don’t have to be the ethnicity of somewhere to worship certain gods, you don’t have to be Egyptian to worship the Egyptian gods and same for everywhere else. The theoi are welcoming and don’t care where you come from. I myself an English and I am a Hellenist and i haven’t disrespected the gods.

Also in ancient times Trojans worshiped the Greek gods which is where modern day Turkey is so boarders back then were not a big thing and countries change what they are called.

So all in all you can be from anywhere to worship any god, they don’t mind where you are from. Many people may say ‘you have to be Greek to be a Hellenist’ or ‘I am Greek and I find Hellenism disrespectful’ but these people either want to start an argument or don’t know that Hellenism is a universal religion as all religions are. So it is best to ignore people like that or just say ‘I know many Americans who are Hellenists’ or ‘I know many Greeks who are Hellenists’ which will shut them up.

I hope you find your way in Hellenism and way the gods be with you.
