Sign Stolen?

Could I put up a sign that says,

In this season of remembering the sacrifice of the Son of God, may reason prevail.

There is only ONE God, the God of Abraham, Isaac, and Jacob, Whose only begotten Son died to save us.

There are angels, who serve our God, and devils, who serve the enemy of mankind Satan.

Heaven is a real place for those who are righteous. Hell exists for those who do not believe in God, and those who die without Him must face everlasting torment.

Religion has been used to enslave minds through myth and superstition, but FAITH in the Lord Jesus is freedom and transcends all bondage. GOD BLESS.

In fact, lots of places have done exactly that. Where I used to live in Kent, Ohio, they regularly gave space to an itinerant preacher "Brother Chuck"who would rent time in public spaces, especially public school yards, to post large signs that said just that, and he would set up a PA system and scream loudly at every woman who walked by that she was a whore/evil for wearing shorts or cutting her hair. Once, just once, a student at the school asked him to leave after his alloted time was up, so the student's group could have the space for their own use, and the preacher punched him and broke the kid's nose. When it went to court, the town told the student he was infringing on the preacher's rights, even though the preacher's rented time was up. We had KKK members preaching on the state capitol steps in Columbus. When I lived in more rural parts of PA and in Amish country, it was normal to go downtown to the public square to see a movie or whatever, and see signs that read exactly that on public gov't property, plus various quotes from the Old Testament, accompanied by preachers screaming that everyone was going to heck or whatever, passing out flyers and such.

The town's rationale was, anytime someone else wants to do the same, they're welcome to, but every time anyone else asked, there was somehow always a "paperwork technicality" or a "scheduling mishap" or, in one case, a "public safety concern" such that no one who wasn't a very devout Christian could do the same.

Seriously, have you SEEN the things posted by the Phelps clan in Kansas? They have marches and parades and such on public property all the time even though lots of people wish they would just go away and find them offensive and disrespectful.

I honestly have no clue where devout Christians get the idea that they are oppressed and discriminated against and can't express themselves in public. It's completely to the contrary of everything I've ever seen or experienced. But with respect to making a display of one's faith in the public square, doesn't Matthew 6:5-6 have something to say about that?​
