tolerance of sin is not a Christian trait. in fact, it's anti-Christian. to tolerate the behavior of others engaging in activities that put their souls in mortal danger also endangers one's own soul. God wants us to love one another. you cannot love somebody and passively watch them engage in behaviors that will condemn their souls to eternal damnation.
there is this nonsensical hippie BS about who and what Christians are supposed to be. in the past 40 years or so, Christianity has been dumbed down to become little more than walking around smiling at the world and being nice to people no matter what they are doing to themselves or others. this is NOT what Jesus taught. Jesus got angry when anger was warranted. being angry about sin is not wrong. tolerating sin is.
Christian love is willing the good of the other which is not tolerating sin. It is not celebrating sin. But it does also NOT persecution and killing.
We are all sinners.
