Is it wrong to put across my point of view forcefully?

Over the years I’ve come to understand that one must put across one’s point of view, on any given subject, failing which it’s usually misconstrued that one’s support is assured whereas, one would have preferred the option of silence lest somebody would get hurt! It’s entirely possible that feathers would be ruffled but in the final analysis, the aggrieved party would appreciate the fact that one had fired from the hip and not resorted to surreptitious bickering behind closed doors. Lekha calls my faux pas –and numerous ones at that – a ‘foot-in-the-mouth syndrome’ but all the same, understands and endorses this behaviour of mine.
Cdr(Rtd) Jojy Kunchattil, a classmate from the Sainik School, had given an invite to all of us through our group mail on ‘yahoo’ for his son’s wedding at Kochi (which was in addition to the personal calls made by him and his wife followed with the mailing of cards). This was objected to by Radhakrishnan –another classmate of ours, a banker and an otherwise carefree guy- who insisted that the two Major Generals from our course should not have been invited in this manner as protocol demanded it. Some guys, including Jojy, conveyed their displeasure in conversation and I realized that they were merely keeping quiet so that bad blood would not be spilled on the circuit! But I chipped in with my mail saying that friendship and protocol are incompatible and the suggestion from my friend of deferential treatment on the basis of protocol smacked of sycophancy. All hell broke loose and Radhakrishnan has signed off from the circuit saying that he does not want to be part of the group anymore. I must hasten to add that it has saddened me as I'd never wanted it to end up in this manner.
It’s my sincere hope that Radhakrishnan comes round, rejoins our group and appreciates my point of view.
