sigh. The way to work with people is not to alienate them. Sure - if you just want to piss people off - throw accusations at them and suppose things. OR you can offer to help them. If I want to save a dogs life - throwing paint in protest (so to speak) is not going to help. Yes - they do put down timid dogs - that is how I lost that shep though IMO to this day many years later - he fine, just a little shell shocked.
What do I suggest? Go and volunteer there - oh wait you CANT because so many people esp on DOL kicked up a stink that they banned volunteers - that went a long way to help the animals NOT!!
You can offer up to foster care - who knows - they might say yes.
Kvetching only gets people so far in the world - we aren't kids and whinging about right and wrong is not going to help - doing something proactive might.
When that is exhausted, then other measures might be appropriate - however, all those people blowing their own trumpets in those threads have not tried anything other than whinging.
