Should religious people fight for equality?

It depends on the religion in question, and on what we mean by "equality." In other words, it depends on the specifics of the situation. Some communities are persecuted due to religion. For example, some Muslim communities residing in majority Hindu or majority Christian nations are religiously persecuted. This persecution may include disenfranchisement, social discrimination, violence, and fear. In such cases, the religious minority communities may wish to organize or fight for equality. Other religious minorities may come under no such attack. Or, it may be an aspect of the religious life itself to be socially separated from the mainstream. In American history, we can look to the Shaker community as an example of a religious community that voluntarily separates itself from mainstream society. It is however a sanction of political secularism that in general, religious affiliation should not result in state-imposed barriers to national social, political, and economic life.
