Yes, it is okay and is still used as a religious symbol. My mother in law follows Buddhism and some of her statues have the symbol on it. She doesn’t eat meat, doesn’t kill bugs (intentionally), believes in non violence and watches pbs kids and other family friendly shows. Like this picture though, the angle on her statues are not the same and there is no hate intended in her prayers.

Edit: Part two to your post: If it was turned from a symbol of peace to a symbol of hate, in time it could return to a symbol of peace again if people chose to believe in it. For now they see it as a symbol of hate, and that’s completely understandable.
