This is mostly nonsensical.

Living your life hunting for reasons to be upset, even if you feel righteous and even if you are correct in your position, is bad for you.

You don't need to assume a person is mean-spirited, ignorant, inconsiderate, stupid, or any combination of those traits just because it's technically possible to read and interpret something they wrote in a way that is unkind toward some entity or group.

Please stop stressing yourself out like this.

You are correct. This website is full of this same dog whistle whenever reddit talks about the Sikhs. People always comment that to imply Muslims may deserve the hate crimes but Sikhs do not.
