It'd be generally advisable not O.o to overuse smileys ^.^, refraining from snarky O.O comments and generally not being a prick ^^. Also, some form of socialisation might help. (Contrary to what some people think, the furry fandom is _not_ an acceptable substitute for a lack of social skills, nor a training ground.)
With all that in order, people might even take you seriously and not just think "Oh god, another one of those".
