First off, Christianity is not getting along with people, it is a decision you make to believe in Jesus Christ, or not.  Practice of religion is different.  A Muslim man can refuse to work with uncovered women, he can go and leave that job.  Acceptance of the economic impact is his 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 and sell those products. Producing a wedding cake (when ones’ religion practice excludes same sex “marriages” ) is not possible.  Freedom in this case is not one of being forced to serve others, the freedom is the choice to refrain from serving others.  This writing reminds me that the author is saying that I should be compelled to serve whatever the author wants, 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, the one demanding the cake would not want it as much.
