Welcome to the board. You have witnessed first hand the true legalistic nature of the WTS. Love and mercy are not at the forefront. Laws, rules and obedience are at the forefront of this religion.
A side note, being a stickler and all: one is not DFd for the actual offense, be it whatever. One is DFd for unrepentance. Officially, on paper, that is. In reality, DFing or the threat of it is used indiscriminately among many elders who are mad with power. Elders do not have Holy Spirit directing them. They're just men...untrained and uneducated in most instances. They let their own prejudices and opinions dictate how to treat people and how to make judicial decisions. (A side note to the side note: not all elders are evil, rotten bastards. There are good men in their ranks as well. It's just obvious from so many bad ones that God is not operating through these men).
From reading your take on the experience, I can't help but think that these men had a problem with you, your spouse or your circle of friends. The level of drinking that you admitted to, while under JW law may require some counseling, it was definitely not DF worthy. They were making an example out of your group. Because you didn't cower, beg for mercy (read: kiss ass) they deemed you unrepentant and they lowered the boom on you.
It hurts like hell, it's not fair, you've been mistreated...but take heart. In the long run, this may be the best thing to happen to you. It's a clean break. Study up on the tenets of this religion. Study its history, its scandals, its shortcomings. Once you see that this is not the "truth", you may come to see that this event was a blessing in disquise because you truly have freedom now.
I know this is gonna sound stupid...but....what is a DH?
I've wondered this myself when I've seen this used. I couldn't figure it out. The only thing I could figure was Designated Hitter. Which isn't a bad idea, if you have to face a judicial committee. Pick someone else to set in and you stay at home...
