How do you find out someone is gay in the middle east? Check the tombstone
Why would you make this statement?
That I don't like gay people and they should be avoided
That remark is very homophobic. No one deserves to die, or even be shunned, due to their sexual preference.
I'm going to take this to HR
I don't think HR would be on your side because your comment is very homophobic and also makes assumptions about people from the Middle East. While it is true there are some countries with homophobic policies, many people from the Middle East are tolerant. And, you should try and interact with some gay people so you can get rid of your own prejudices.
