People can have opposing views about how to treat people equally, regardless of gender, sexuality, or ethnic origin. A famous historical example is the equality feminism vs difference (diversity) feminism, which is directly opposite views with the exact same goal. One view is that women and men are equal and any difference is so minor as to not be significant, the other asserts the differences and promotes them as being important and of equality worth. The effort to achieve equality are for those two groups opposing efforts where every step forward for one is a step backward for the other.

Intolerance against different opinions oppose any dissenting views that shares the same goal but not the strategy to reach it. Equality feminism vs diversity feminism, open source vs free software, and so on.
