You mean, "their pursuit of forcing eveyrone else to be as virtuous as THEY THINK they are." If I enjoy a 32 oz drink, and someone else thinks it's virtuous to drink at most 16 oz drinks, they won't convice me a 32 oz drink isn't virtuous. If someone thinks my drinking some wine isn't virtuous, I'll point to Jesus making wine from water. Is there ever virtue in forcing others to do things they don't want to do (when their actions harm no one except arguably themselves)? I say no.
