Judge not

Often when a Christian speaks out against sin, some variation of Matthew 7:1 might be quoted to them by someone who informs them that they’re not supposed to judge. In the same way that most drunks know nothing of the Bible other than that Jesus turned water into wine, this verse is predominantly quoted by non-Christians or nominal Christians who know little or no other Scripture.
The implication is that they believe Jesus was instructing us to universally accept or condone any lifestyle or teaching.
