If people are using the exit doors then that is their prerogative. Because they are exiting does not mean that they are automatically right in doing so. Let us not forget that far more people rejected the teaching of Our Lord when He walknor Denys the earth, both Jews and Gentiles yet there is not one shred of evidence in the Gospel  or the rest of the NT that He changed His teaching or ameliorated His Gospel message to accommodate the misgivings Jewish or secular society had about it.
When the rich youth could not give away his worldly goods in order to be saved Our Lord didn’t say, “oh well, you don’t have to give all of your wealth away.” The man asked the question and Our Lord gave him ?His uncompromising answer. In the same way in John 6 when some disciples left Him  over the command to eat His flesh and drink His blood, again He never compromised He let them go.
The Church can never rejig its teaching to accommodate the mores and values of particular eras.
