Don’t assume all evangelicals are conservative.
I would put it this way, don't assume anyone who says they are a Christian - are a Christian. Just a few examples: a born-again Christian is not pro-abortion/pro-choice. A born-again Christian does not support the gay life style or gay marriage.
"Beware of false prophets. They come to you in sheep’s clothing, but inwardly they are ravenous wolves. By their fruit you will recognize them. Are grapes gathered from thornbushes, or figs from thistles? Likewise, every good tree bears good fruit, but a bad tree bears bad fruit. A good tree cannot bear bad fruit, and a bad tree cannot bear good fruit. Every tree that does not bear good fruit is cut down and thrown into the fire. So then, by their fruit you will recognize them." - Jesus speaking in Matther 7
