To answer your question, I will vote for and support politicians who share my values. 
Those values may be based on religion or a life philosophy formed by experiences; that's fine with me.  I vote for those who share my values just as everyone should.  If you want free stuff and higher taxes, vote for the politicians who will give them to you.  If you value less government in your life and want to keep more of your paycheck, vote for politicians who will support those values.  If you want to kill unborn babies and legalize recreational marijuana, vote for candidates who support those issues.   I'm not sure how a bakery qualifies as a religious institution.  What has religion done to you?  You seem to be an anti-religion zealot.  How do you define "religious dogma"?  Can one be religious without being a zealot?  Can one be an atheist without being offended by others' religions?
