The actions/views of writers/artists should be separate from their works. Or do we think about the actions/views of the person who's packing your groceries or flipping your burgers? Should we give them our money... That way lies madness!
Things like child abuse, rape and even murder are enraging. And people should be punished for them harshly (I feel that anything short of a tortuous death is getting of light in this regard, but I disprove the death penalty, go figure), but income from legal activities should not be further punished by the public imho. You can make a choice whether you want a product by person X or not.
A further problem is regarding 'famous' people and accusations, the fame surrounding them makes them a better opportunity for attention seekers to make false claims. Don't get me wrong, not every accusation is false (far from it), but I'm always skeptical especially when 'famous' people are involved.
The folks spewing hate, racism, etc. I just find sad, as long as they don't do do the other horrible things, if they get in my face they might have a demonstration of fist meets face, face meets ground. When dealing with such people I always think "When making something foolproof, they keep making better fools!". Things are different when these kinds of people start moving into public office...
As for the people living together (of the same sex or not) who aren't romantically (or sexually involved), these are perfect solutions for combining resources, companionship, mutual support, etc. The (single) guy living with his mom... Hits close to home ;-) I am that 38 year old single guy that rented a house and invited his parents along, not because I was financially bad off, but because my parents needed support (after all the medical stuff my dad went trough he's now the $6,000,000 man, we can rebuild him!) and after having worked 45+ years the pension my dad build up wasn't exactly luxurious. Having worked a day in an 'old folks home' 25 years ago I can say I truly don't wish that on my parents. My mom still cooks, cleans and does the groceries, any attempt to change that is thoroughly shot down by said mom. I pay the bills, do the heavy lifting (something I somehow have to enforce, sometimes they still act as if they are still 18 or 45) and provide technical support ;-) This arrangement is beneficial for everyone involved, although you sometimes get those stares from people that say "He still lives with his parents!", I have a thick skin ;-)
Edit:
Changing people's views isn't as hard as it is made out to be, but it requires manipulation. It can be as simple and innocent as "Take an umbrella." vs. "Take an umbrella, because it's going to rain cats and dogs according to the radio.". People just don't change their view because "I said so!", they need reasons. And some people need a lot more manipulating then a reference to today's weather report... But honestly, a lot of it just isn't worth your or my time, because it's a bottomless pit, on the other side everyone else is also manipulating the same person. People are gullible...
