You have the right to think any way that you want to think. Of course this means to think good thoughts. When you think bad thoughts. You are going to get in trouble.
So you should think in the right way. But if you do not agree with what everyone else is saying. You have a right to think in any way on that subject that you want. You have the right to say what your thoughts are.
Even if no one wills listen to you. You still have the right to your own thoughts and to think in any way that you want to.
Think your own thoughts and believe your own beliefs. That is what freedom is all about. As long as you are not doing criminal things. Than tell others if you want to. Your thoughts and how you feel. That is your right when you are a person.
