As opposed to the intellectual maturity of such a ridiculous comment?
Please. There's a distinction between something being intellectually stimulating and something requiring mental gymnastics. Calvinism has no shortage of the former. Your posts seem to stem from the latter.
When you're ready to stop chucking batteries from the sidelines and get in the game, feel free to grab a helmet and take the field (unless of course you're the non-helmet type).
I like your tag, Fru. Amen.
