Everyone falls short. We can't let our weaknesses become excuses or to allow them to redefine the goal.
Criticism is often constructive, even if done in a back-handed way.
Here's a test:
Would you support a practicing homosexual pedophile rabbi as long as he was for lower taxes and voted Republican most of the time? I mean, after all, he is mostly a Republican, right? If you don't support him, by what criteria do you put him down?
Do you really think that is a meaningful and realistic example to make your point?
