He is engaged in delusional thinking. Conservative churches in my area are growing steadily while those with the liberal bent are declining quickly.
Our local first baptist church started ordaining women to pastor and be deacons in the late 1980’s, big drop off in attendance and they were booted out of the local and state baptist conventions. Today they are losing members at an alarming rate. They go on their merry way like all is well and debating them as to where they will draw the line on any sin is like pinning jello to the wall. Oh they love everybody and we can’t have a standard because we can’t say if something is a sin or not, God is the final judge and the Bible doesn’t really mean what it says.
There are loving ways to warn people about sin (and back to the aiding love of the Lord), and in an overall healthy Christian body they should prevail, but they definitely do warn about sin. They don’t just warn about not being nice. Having a godly balance is the key. A ministry that does nothing but chew people out won’t prosper very much either.
Yes, quite often standing for nothing definite means losing your reason to be there in the first place.
