The gentleman made a classic non sequitur.
I have heard Rechabites and those Christians who abstain from alcohol in the Church make this unsubstantiated claim on other occasions. They do the Faith no favours by making a dishonest point.
Romans 14:3 " ... and those who abstain must not pass judgement on those who eat; for God has welcomed them. 4) Who are you to pass judgement on servants of another? It is before their own lord that they stand or fall."
1 Timothy 5 (New International Version).
23) "Stop drinking only water, and use a little wine because of your stomach and your frequent illnesses."
Incidentally, the word 'temperance' means 'moderation' and not 'abstaining'.
