Common meaning:

Something that is strange and not normal.

Hidden meaning of the Equity religion: 

Attacking and disrupting sexuality that Western society considers normal.

Discussion:

One of the goals of Equity is to destroy anything that Western society considers to be normal including sexuality. 

The reason the Equityists want to bring about the destruction of the West is because they believe the system is so oppressive it cannot be redeemed. It must be torn down to the very foundations in order for us to have any chance of building something equitable for oppressed groups.

One of the ways the Equity believers attack the West is by using the word queer. The word is not used simply to say that something is different from normal but that normal is evil. The end goal is not to alter what people think of as normal to include queer but to get rid of everything normal by making everything sexually queer. 

The word queer is used to attack any sign of normality.
