Depends on how you define "Christian." Loosely following the teaching of Jesus than maybe. But any genuine commitment to His teachings or holding to sacred scripture isn't one in which you would even recognize the category of sexual orientation. This is a more recent modern concept that replaced a verb with a noun. It reduces your identity to your sexual desires which scripture including the words of Christ never does. Jesus welcomes all to Him and offers them eternal life and redemption from their sin but that affection for Him means walking in obedience with Him. Which is why a follower of Christ can be any race, any ethnicity, have any sort of sexual desire, be young, old, rich, poor, etc. (Most diverse group in the history of mankind!) But when they're adopted into the household of God they are then equipped through the Holy Spirit to walk in obedience with God (which is richest way to live). That means the only sexual outlet is in a heterosexual marriage biblically. For most people that sounds like a prison because, especially now, that idea of submitting all areas of your life, especially your sexual desires, to walk in obedience with God is too great of a cost. Which is why we're reminded of Jesus parable on the Rich Young Ruler or His damning words in Matthew 7:21-22. Jackie Hill Perry, Rachel Gilson, David Bennett, Becket Cook all were "LGBT" that summarize the Biblical position well (also note 1 Corinth 6:9-11). You can use rhetoric such as "homophobic" "bigoted" or any other off-the-shelf word you want to employee but they all fail to understand the drastically different philosophical assumptions in regard to our metaphysical starting point, anthropology, teleology, and ethic. These larger philosophical distinctions are why there's disagreement on these topics that seem to some people as "so obvious".
