Nothing wrong with that, but during the Malay Congress, they start attacking other races.

During other nons congress, where got they attack the Malays and make this or that demand?

There is nothing wrong with a Malay Congress. You can congress all you want, whether in the literal / main congress meaning or the other / old congress meaning.

But when in your single race congress, you go and eff other race directly or indirectly, then why should you be hurt when the nons go and tell you to "congress" your own self?

Seriously.
