For I rejoiced greatly, when the brethren came and testified of the truth that is in thee, even as thou walkest in the truth. 3 John 1:3
It’s a given, if you speak Truth someone will lash out at you. You will find out where they stand. Their true colors will shine through. But do you shrink back in a hole never more to proclaim the Gospel? No! If anything, you speak a little louder! You shine a little brighter! You stand firm in Who you have believed! Paul said in 2 Timothy 1:12, For the which cause I also suffer these things: nevertheless I am not ashamed: for I know whom I have believed, and am persuaded that he is able to keep that which I have committed unto him against that day.
Don't let a little backlash on the Truth you speak cause you to discontinue doing what God has commanded!
