No it can't be said about any drug (well you can say it but you'd be wrong).
There's no way you can compare the social aspects of E and, say, DXM. If you took a survey right now you'd find far and wide that most E users prefer to take it in a social setting (and like me the are probably passionate about that point) while DXM users probably lean towards home alone or just don't care.
I also can't imagine most coke heads enjoy sniffing a few lines and having a nice, quiet evening at home.
Because of their effects, some drugs simply ARE better suited to social occasions. You might find many of them skew towards "either way, don't care) but I'm sure some would poll strongly in one setting or the other.
And I'm glad, diversity in "mood altering" substances is a good thing!
