Namaste,
Not really anything to debate, but there is some stuff to discuss.
Firstly, I'm happy for you, in that you've seen through what seems to be a common trait amongst some groups of devotees. It seems so difficult of a breakthrough for some ... to realise that others may have a valid point of view, and maybe it's a good idea to listen. The root word of ignorance is ignore, after all. Ignore means to not listen, so ignoring means you stay ignorant.
I've seen bits and pieces of ISKCON for 45 years now. I liked the days when devotees danced on the streets, but back then when I went to a local temple, the proselytising turned me off. Then there came a period of deception when ISKCON devotees dressed in suits and ties out on the streets, pretending they were something other than who they were, raising funds under false premise. I had one encounter where the person lied (partly) about being an international charity, and hedidn't know I knew what the ISKCON tag on his suit meant. I didn't confront him, but refused to donate money, and walked away, losing more respect.
But then the long period of immigration started, and Indian immigrants started going to the ISKCON temples, not as members of ISKCON, but as devotees of Krishna. It was the only thing available. So that developed a variation in the temples, with more Indian influence wherever more immigration happened, and less in others where the converts were still the majority. Generally, it was a mellowing for the entire group. A person could go and not get proselytised at. I think it helped show the converts a humbler attitude, by example.
My last encounter with ISKCON was in India, where a small group was proselytising outside a large Murugan temple in South India, where Siva and Murugan worship is so popular. I found that insensitive. Most temple devotees just ignored them. I really felt like going up to them, asking them to drop the books somewhere, and coming with me into the temple to receive the darshan and blessings of Lord Muruga, whose Vel dissolves ignorance and ego. But I figured they wouldn't be able to do that as it would be straying from their purpose: to proselytise.
My city (Edmonton, Canada) has an ISKCON temple. I've been 3 or 4 times, but always on a weekday morning when it's empty and Panditji is busy. I took a fresh flower garland once, and just sat in front of the Gods for half an hour or so.
All in all, ISKCON has done more good than harm, by being out there, and providing people with an alternative to western faiths. I think some of the heavy proselytising was because of converts bringing along their subconscious minds with that, and being an exception to 'Hindus don't proselytise!' But it's all good now. You're an example to that.
