Why are american people so against arranged marriages that you have to take it out on me?

I think it must of been someone here who found out my address in san jose and letted these people know because they are standing outside my house with signs. Those sign says Arranged marriages are barbaric and should be made illegal and some of them say the government of the U.S needs to ban arranged marriages or more soldiers will die. Why are you so against arranged marriages that you have to take it out on me and embar me ????
