It is unfortunate. God has called us to love one another. 1 Cor 13 says if we speak all knowledge without love, we are just making noise.
Yet, I am likely one of the worst offenders. Don't get me wrong, I love many people. I have many friends and I am pretty involved in my church.
I pray with people, I talk with people. I have helped people move, I have help paint their houses, I have mowed their yards, I change flat tires for strangers on the freeway.
Perhaps that will be taken as bragging, I hope not, because I have nothing to brag about. I pass up many opportunities and could be doing a lot more.
The reason I say these things is to share my heart.
A well known atheist ( Ellen Johnson ) who was actually quoting another atheist who is now passed away once said "You must really hate someone in a special way, if you know they are going to hell for eternity and you don't tell them how to keep from going there". An atheist said that. Now of course she doesn't believe in God, Jesus, heaven, hell or any of that, but she understands why some Christians evangelize. Perhaps I don't always say things in the most loving way (I'm working on it, I pray about it) but some of us feel that if we can keep someone from going to hell, that is showing them love.
Jas 5:20 let him know that he who turns a sinner from the error of his way will save his soul from death and will cover a multitude of sins.
