The people at the bar down the street are not engaging in pseudo-intellectual discussion when they discuss an instance of the current foreign policy that was in the news that day, even though they know nothing about political science and the art of foreign policy. Your definition includes that and is thus just silly.
Just entering an opinion on a subject you don't know 'enough' about is not pseudo-intellectualism. Pseudo-intellectualism is making it seem like you have significantly more intelligence on a subject than most other persons or have put significantly more thought into it, often connecting a subject to other subjects, and are thus qualified to make more informed comments on these subjects. You can lend more credence to your comments by using the correct academic vocabulary, but can be caught as a pseudo-intellectual by using it in the wrong way.
