Fortunately, LGBTQ struggle is mostly avoids destruction and wounds from either side. Unfortunately, mass street protests very often do not. Even if every participant of such a protest had a very good reason to feel infuriated and destroyed stuff because of that, I say that it's not good for them, it's corrupting them. AFAIK Rosa Parks didn't break a single window.

The lure to use the fury of the crowd gathered for a just cause is always strong for their leaders. Holding this fury back and not allowing it to turn the gathering into a riot is always hard work for those leaders who strive for a non-agressive way to protest.

Same applies online.

So, again, which gay rights protests has this happened at recently?

Or is this that thing where shop windows are more important then lives?

More important than lives, no. Important nonetheless.
