Because? We promote people to get high and say its ok. We promote public indecency and say its ok. What is wrong with a priest on a motorcycle compared to these? I honestly don't understand the problem when compared to the others, so I am sincerely asking you to explain. Probably better in a PM so we don't derail the thread too much.
There's no real topic in this thread, so we won't derail it too much.
I'm well aware of your fervent opinions on "getting high" and "public indecency" as expressed in other threads (as well as your emphatic disagreement with alternative opinions) but they really don't apply everywhere you think they do.
My protest is not that a priest is riding a motorcycle: I've seen archpriests ride motorcycles in India wearing cassocks with red piping, jeweled pectoral cross, and kalimavkion. That's really not a problem for me.
But I can't imagine a situation in which it would be appropriate for a cleric to wear sacred vestments while riding a motorcycle. Generally their use is restricted to liturgical rites conducted within the church. Their use "outdoors" is quite restricted in just about every tradition I'm aware of. Even in the church you're not "free", while you wear them, to conduct yourself as you might were you only wearing a cassock. What was that priest doing while riding a motorcycle that required wearing a phelonion and epitrachelion? The photo just looks strange and, barring some legitimate reason that would surprise the hell out of me, irreverent.
