A true love for one’s fellow man would be expressed by leading unbelievers to Christ without any distraction of diversity. Narrow is the gate. We are one body, not diverse bodies, accepting one another.
There also is confusion of universal atonement with universal redemption. Our Lord Christ Jesus provided an atonement of all humanity to God the Father, but the redemption of each sinner happens through faith in Christ. Faith absent of Christ fails to provide redemption nor does it reconcile any particular soul to God the Father.
Except when Scripture is not reverenced as your supreme authority and you are your own.
