I agree with you that most of us would not "like" to attend a stadium where we would have to read "Islamic stuff". But I tend to think that what freedom means is to allow the freedom to do so and then the natural consequences of such acts will prove whether or not they will be accepted in the society. If and when a religious statement is posted that offends too much and people refuse to attend the stadium, then those posting it will KNOW that it is not acceptable.
As a nation we have apparently chosen to be acceptable of all religions. We are telling our children to be "tolerant" of all religions on one hand... and then we say "but don't remind me that I am advocating tolerance by making me read a sign reminding me that these other religions are tolerated here." It's hypocritical and I think very confusing to kids. I have never been afraid to allow my children to see that other religions exist and in some places seem to thrive. I am confident enough that since they have known Christianity, they will choose it over the others and be a stonger Christian for having chosen it freely rather than having it crammed down their throats.
It seems that schools are not afraid of requiring students to read the Koran, etc, but are very afraid of allowing them to read verses from the Bible. Why is that?
Well said, Apple Pan Dowdy. Are we all so confused religiously that we can't stand to look at a sign relating to what someone else believes? The church has freedom of expression, just like anyone else.
