We have been on three Silversea cruises since 2013 and have had little in the way of problems. Although we don't advertise by being "obvious" most people knew we were a couple and had no problems with us. We did a variety of itineraries including an expedition to Greenland and Arctic Canada which turned out to be one of the best cruises we had. Unfortunately, since RCCL took over, the prices have shot up dramatically so we started looking at alternatives. Maybe someday we will return. As for snobs, they exist everywhere and most people laugh at them behind their backs. Thankfully, our cruise experiences have seen little of those.
