I do my best to avoid this kind of crap, but sometimes it creeps up on me. When it does, it's a lot harder than you might think to not become part of the shit show yourself. Because you see, shit shows are like tornados. They pick up everything in their path and deposit them willienillie. And suddenly, for no reason you can't, or don't function in the normal way because you're so busy reacting to all the shit thrown your way. You can't concentrate, things get lost, you forget things and make lots of simple mistakes because you are unable to pay attention to details when all you're doing is dealing with the shit that's constantly thrown at you, hitting you and mucking up your path.
So what does one do when in a shit storm? Cover up the best we can in protective clothing? Pretend it doesn't bother you? Fight through it to do what you've got to do while saying to yourself, "I'm so tired of this shit!" It's hard to say what the best response is.
With some people it's easy to say, "stop, lets regroup." But others are really committed to their bullshit and are going to cling to it like their life depends on it. And then there's the stealth bullshit too, that comes from those who make a show of being put together, but are really just flinging shit.
Honestly, for me, I try to distance myself as much as possible from all the shit. It's like I use to tell my kids, "no stupid." Don't do stupid things, don't hang out with stupid people. I think the same rule applies to bullshit and correlating shit show.
Avoidance is possibly the only solution.
