Let's see, the question was "Do ultraconservatives do more to keep folks out of Heaven then to let them in?" (The underlining is mine).

Well, let's look at the question more closely:

Do ultraconservatives first keep folks out of Heaven and then, at some later time (maybe after all the ultraconservatives get there first) let the other folks in?

Do ultraconservatives do more to keep folks out of Heaven than they do to let folks in?

The former suggests the ultraconservatives will have taken over Heaven and made themselves sovereign over God.

The latter suggests the kind of situation Jesus referred to in Matthew 23:15-16...

"Woe unto you, scribes and Pharisees, hypocrites! for ye compass sea and land to make one proselyte, and when he is made, ye make him twofold more the child of hell than yourselves. Woe unto you, ye blind guides, which say, Whosoever shall swear by the temple, it is nothing; but whosoever shall swear by the gold of the temple, he is a debtor!"
