Majority of the users on this forum are Singhs anyways. If you see something, you're welcome to tell an Admin or Mod using report feature and someone will eventually address it. Likely will get the individual put under Quality Control or a suspension/warning.
Using slurs is against the rules. Period. If you've had any formal education you'll know how to formulate your own perspective. If you can't, then perhaps you should enroll in a University or in an adult education course on critical thinking, writing and speech.
If Mods/Admins do their work, there will be crying, if they don't then there still be crying. This is a Sikh forum, not a place bound by rule of law but instead what the Admin dictates as being the rules.
