Short answer: No.
Long answer: You see, we're against degeneracy. Do you know why? It's because degeneracy is against the natural order. Logic says that we should then be against all things that are against the natural order. Any person with a 'fursona' is partaking in activity that is morally disordered.
Therefore, we should not ally ourselves with furries. This is because we don't want to desensitize ourselves to things that are disordered, lest we might find ourselves losing some members to them.
