I am a strong supporter of sincerely (non-defensively) considering "outside" criticism (of evangelicals, conservatives, bald dudes, whatever) and of prioritizing inner reform over outward transformation.
But even I find it very difficult to sincerely consider an outside criticism if it seems like the author does not *desire the good* of the criticized group.
If your real argument is, "these people shouldn& #39;t exist" or "should not exist in civil society," you won& #39;t be taken seriously except by people who already agree with you. Even if you have valid and important criticism to offer!
So, when you criticize, I recommend make it a point to consider the desire of your heart. What do you hope will happen? What do you desire for these individuals? Can you even envision a form of the Good for them? If not, maybe just keep it to yourself.
