I suspect the folks who want to take down Pride will necessarily have to come after MG. Their leaders have nothing but grievance policies to offer. Once the stage is set and there's not enough opposition, you can bet on it.
Same people who stand in the middle of Bourbon St with a giant cross and a bullhorn - they are widely ignored by the crowd.
Not to say that MG is bulletproof - both ends of the political horseshoe have their own stupid agenda - remember the Tales of the Cocktail lady who had to resign because she rode in Zulu (blackface)? Those two ends could converge in a firestorm of stupid and cause some problems.
But I think Widge is correct - as long as locals have the final say, MG isn't going under any time soon.
