I did when they posted what religion they are.
I don't remember them all, but some are Christian.
You don't have to be a “denomination” to be a Christian.
Paul, Peter and those other 1st century guys didn't belong to a denomination.
They were followers of Jesus Christ.
They were Christians.
Now it is possible when you ask people their denomination, they don't tell you right away because they may have asked you several questions that you only gave an emotional! response! and not an answer.
Perhaps if you gave simple answers to simple questions you would get them back.
And as an end note, it's not my job to watch closely for you when someone declares how they describe their faith.

It was the differences in man's understandings of God, as manifested in the different denominantiions, that caused me to ask if God was real and if He was, which of the teachings is His teachings.
That is not a denomination!
