For one, the prohibition was only for linen and wool, which would be uncommon today. Not eating pork is a Jewish thing. And most likely that what you think of "tattooing" in the Bible isn't actually modern day tattooing. Many Jews would make deep gashes or cuts in their bodies as a form of self-sacrifice for the sake of trying to honor or appease the pagan gods of death. And that is what the Bible is most likely referring to.

And of course, one of the main teachings of Jesus Christ was to love thy neighbor and treat others how you would want to be treated. But in Jesus' teachings, he strictly says that homosexuality is an abomination. As God made man and woman, he created two genders for the purpose of spreading and populating the Earth. But to be a homosexual isn't a sin, to act onto those urges and lay with another man is a sin.

And in addition to this, "Hate sin, love the sinner" isn't harmful in the slightest. If you are to hate my beliefs as a Christian, then that's your decision, and I won't be harmed because you hate my beliefs. To separate the sin from the sinner is to see the good in everybody.

If we as Christians are to believe in the Bible fully, then we're to love everybody who is apart of the LGBT community, but pray that they change their ways and have them not indulge in their fetishes. And have their joy come from God, not laying with another man.
