Ah, that's right. For you everything is a religion, isn't it? Jobs, philosophies, sports, habits -- anything anyone spends time on is a religion to you.
Can you even name some belief or idea that can't fit your concept of a religion? I can't.
Things become religions for people when they place improper belief in them. When people consider fictitious or potentially fictitious things as truth, and then start to adamantly believe and trust in them as truth, that's when they have a religion going for themselves.
Any and all ideas that a person has, that he doesn't start to adamantly believe in or trust as truth, may not be a religion for him. For example. A beautiful butterfly may cross one's path. It might intrigue the person for a moment. But then the person goes on his way and forgets about it except to mention it to a few friends. No butterfly religion.
A lepidopterist on the other hand, has made butterflies his religion or one of them.
Interestingly, most people would call a lepidopterist a vocation rather than a religion. Is a vocation a religion in your idiolect?
No point to argue with this imbecile. By his reasoning, study of bridges is a sect of civil engineer's religion.
Never mind cosmologist studying black holes...
He redefines common English terms to fit his skewed worldview. He is delusional and he knows it, but he tries to convince himself that he is not by inventing "new scientific" terminology and attacking people who point out obvious holes in his "biblical science".
How silly you have become. Don't you realize that anybody who studies bridges, and then adamantly believes stuff that is blatantly not true about the bridges he has studied, especially in the face of being shown that it is not true, has a religion going for himself? His religion might not be a dangerous one, he may not be harmful to himself or others, and people would not even recognize, generally, that he had a religion going. But according to the definition of religion in the dictionaries, that is what he has.
Since you like to express faith in meanings of words that are not dictionary accurate, and then pick on people who use correct definitions, everyone can tell that your formal religion must be totally wrong, just like your informal anti-dictionary religion.
