Being "religious" or "religion" is not confined alone to belonging to a Christian church or group that follows the principles set up in the Bible. It can and is applied to "any system of beliefs, practices, ethical values etc. resembling, suggestive of, or likened to such as system" — (Websters New World Dictionary of the American Language).
When one writes "But you don't have the right to impose your narrow, intolerant religious dogmas on people different from you." (June 7, Free Press), it is an ethical value that is as religious as those who speak against gay marriage.
Religiously, I have as much right to speak out against gay marriage because of what I believe, as a person who religiously speaks for it. I will continue my right to believe that holy scripture speaks against same sex marriage and will continue to speak for marriage alone between a male and female.
I will continue religiously to follow the Biblical words of God my savior who loved me and died on the cross for all of my wrongs and sins.
