RebE, would you be happier if Avira used only CAPITAL LETTERS? Or the true sign of respect is big letters for some but small for others? And whataboutthatTorahdoesnotusuallyhavebiglettersforanyoneandnopunctuationmarksalso
At the end, it is a convention. Avria can make a disclaimer that all Rabbis should be considered properly capitalized (if he thinks so). R Gershom Kamenetsky in a preface to his non-book says tht he is using R, and it is up to you whether it should mean reb, Rav, Rebe, Rabeinu, etc
