These are the rules. This is how the world works. Opinion based on religious beliefs are not based on facts. Credibility does not come from religion, but the ability to form opinion based on facts. When people don't understand this, they get put at the kids table.
Some people don't understand why they are removed from the conversation and treated like kids. They think that it is due to their religion or political affiliation. These people need to learn that if your opinion is not based on facts, then they do not deserve to participate in the conversation.
This is why there is a kids table. At the kids table, you can base your opinion on anything your want and reserve a seat to your imaginary friend. However, to deserve a spot on the table for grown ups, opinion must be based on facts. People need to demonstrate that they understand this.
When somebody doesn't understand this, they get removed from the conversation, regardless of which title or background they have. In order to run the world, opinion has to be informed by facts. Otherwise, the seat is at the kids table. These are the rules. Decides by whom? Those who run the world.
