That may have been their stated objection, but the broader pattern belies this. The broader pattern is "make life as difficult for the poor, middle class, and the minorities as possible."
Why must you accuse your intellectual opponents of being mean and evil? Why would they be so cruel and irrational? Do you have any real reason to believe you are any better than them?
At the end of the day, though, the "why" of their cruelty is not all that important. The fact is that they are evil, and relish in it.
