Right. And how exactly do you imagine this going down? Let's say the sale is called off and by some miracle protests actually happen (they won't).
The Glazers pull the plug and drive away the buyers. Protests happen. The Glazers get uncharacteristically scared and call back all the buyers whose time they just wasted and beg them to come back, which instantly puts them in a disadvantageous position. They finally sell the club and it's happily ever after.
Do people really believe this?
If they decide they are not selling, that's it. They will probably soften the blow by lying again, like they did after the Super League fiasco, and buying <insert marquee signing name>. Fans will move on and it's business as usual.
