Heh. That's the most negative response I've ever heard about this, actually significantly worse than my sister's. It might be partially I was brought in a family where the belief was that education trumps all. My parents were perfectly understanding. My sister was less understanding but we still got along fine after. Maybe she cut me some slack because I completely broke at the time I dunno, but in any case your assessment of the situation isn't accurate.
I also didn't bother going to a wedding of a buddy's that was in Florida. We also still get along just fine.
Now let's extrapolate that response to this whole Pride-Ford fiasco. Many Pride supporters are adamant that Ford should go to Pride. They hate the guy, yet want him to go to their fete anyway, and are insulted when the guy they hate doesn't want to show up. It just doesn't make any sense to me.
As for "few occasions more important than weddings", well, that's your perspective. I am common law married, but won't bother with a formal wedding party, since I think it's an incredible waste of money. My favourite wedding celebration I've gone to so far was a potluck meal in a backyard, with about a dozen people there.
Even if I were to have a wedding, I'd only invite close family and friends and it'd be in our backyard, too. Perhaps we'd splurge and spend a few grand on catering and decorations, but not much more. Also, given what I said above, I wouldn't be at all insulted if out-of-towners didn't make it. It's just a party after all.
If I ran Pride, I would say all are welcome, and I'd extend an invitation to Mayor Ford just to be polite, but actually I'd be pleased if he didn't show up.
Bingo.
