The line being the answer to the questions: to what degree should you tolerate intolerance, to vote for voter intimidation, to call incitement to violence a mere difference of opinion and to be inclusive of exclusivity.
And do be aware that a person who would jail his opponent is never going to be so tolerant of you as you might be of him. It is the position that calls for tolerance only so long as it is weak.
I might suggest that an industry with a very small number of the exact population being targeted should do some serious soul searching about exactly what free speech (if campaign contributions are speech) they are standing by.
