First off, Christianity being attacked  is not getting along with people, it is a decision you make to believe in Jesus Christ, or not. 
Practice of religion is different. Any man/woman can refuse to work with uncovered person, they can go and leave that job. Acceptance of the economic impact is a free choice also. A cashier can decide not to work where he/she is forced to sell bacon. A store owner can decide not to stock or sell objectionable products. 
Freedom in this case is not one of being forced to serve others, the freedom is the choice to refrain from serving others. Is the author saying that I should be compelled to serve whatever the author wants and that I have no choice?
Perhaps if the wedding cakes for those who wanted to force the bakers to produced had the verse Romans 1:22 and 26 or 27 scripted on the icing, the one demanding the cake would not want it as much. Will this be rejected again?
