I'm totally agree with you, everybody has different point of views. All of them must be tolerated, but there are limits.
The question is, where are the limits?
In general, the limits are the border of my property. If another person, or a neighbor, causes disruption on my property that I don't like, he is harming me, and needs to stop.
My neighbor can't sit there on his property with his pistol, and shoot into my house. Sure, he is doing his own thing on his own property. But it is harming me. Same with loud blaspheming from his property.
The steps are:
1. Ignore any little thing a neighbor does. We all irritate others at times, without trying to, or even without realizing it. Give him a break;
2. When it becomes too much, in a nice way tell him that he is hurting you. Just tell him, so that he can think about it on his own, and stop on his own;
3. If he won't stop; start NOTICING him to stop... all the while keeping records of what is going on, and especially the NOTICING part. Include other people as witnesses as appropriate. Don't hide that you are doing all this record-keeping. It might be enough to dissuade him from continuing;
4. After several NOTICES over a period of time, file a damage claim against him, in common law court, man-to-man.
Of course, if he is violent, use whatever lawful processes exist to stop him right now. You will find that in most countries, self-defense is allowed. But be sure it is self-defense. And have witnesses, videos, and all kinds of records of the whole affair.
This might include the Governor and law enforcement of your State, if they lock you down for vague reasons. There is no law that allows them to lock you down. And even if there seems to be, it is not a lengthy lockdown. In addition, since the law hasn't been tested, it might be an unlawful law that needs to be taken to court. Even government people aren't allowed to do things that are unlawful (unconstitutional) to you.
