“But the adjacent homeowners did nothing “
The adjacent homeowners have been living next door to those freaks (Westboro) for how many decades now? They should either be used to the crap or have long since moved.
That statement assumes everyone can move if they so desire. I know people who cannot afford to move; they would be in an untenable situation should they be unfortunate enough to live next to these freaks. And living next door to them doesn't mean they are used to it.
I'm not used to the hordes of ILLEGAL aliens who parade across my property on their northbound trek to steal American jobs and entitlements. I'm not used to California's anti-business climate or its politics, but I cannot afford to move it as I have an established business of over 30 years and do not wish to start over again in another state.
You can live in adverse conditions and not get used to them. And you can be stuck living somewhere even though you may hate living there.
