You are grossly mistaken as to the identity of John Mark. Any Sunday School kid can tell you that the "beloved disciple" is the apostle John, not John Mark who wrote the Gospel of Mark and is mentioned a couple of other times in Acts and by Paul in his letters.

The apostle Peter warned us about people like yourself in 2 Peter 3:

15 Also, regard the patience of our Lord as an opportunity for salvation, just as our dear brother Paul, according to the wisdom given to him, has written to you. 16 He speaks about these things in all his letters, in which there are some matters that are hard to understand. The untaught and unstable twist them to their own destruction, as they also do with the rest of the Scriptures. 17 Therefore, dear friends, since you have been forewarned, be on your guard, so that you are not led away by the error of the immoral and fall from your own stability. 18 But grow in the grace and knowledge of our Lord and Savior Jesus Christ. To Him be the glory both now and to the day of eternity. Amen.

You are one of the "untaught and unstable" who twist the words of the apostles to your own destruction.

For those interested in a more biblical understand, here's a very short historical fiction about man who was gay:
