We already have an American flag, which represents all of us. Why do some groups feel that they deserve special treatment? Equality is good. That isn't enough for some.
Take the ordeal with the bakery. The bakers didn't refuse to bake a cake. They refused to write certain things on it because it went against their religion. Muslims are allowed to outright refuse to do anything for LBGT, citing religious beliefs, and they get left alone. The left won't even discuss that.
The thing is, it's not enough for some to be equal and be allowed to marry and live their lives like everyone else. They demand that people bend over to their beliefs and ignore their own. When some liberals stated that they would refuse to perform at Republican functions or that they would refuse to sell clothes to Melania, no one sued. When liberal coffee shops and restaurants refused service to Republicans, no one sued. They just went elsewhere.
It's always okay for the left to discriminate against anyone who has a different creed than they do. They push their beliefs on everyone and won't stop till everything is done their way.
We don't need special interest flags flying anywhere. They can fly them at their homes or businesses but not at any government office. Why can't they just be Americans like the rest of us? Why do they demand more rights than the rest of us?
