try and vs try to

The much preferred version would be:

"It's always a great day when liberal loons try to sound superior."

In fact, I would say that "try and" is grammatically incorrect--although I know you argue that it is a register situation.

My feelings are that “register” is being used to excuse poor grammar.

In any case, I wouldn’t make anything of this, except that it sounds ignorant…and it was used in a post calling me ignorant…so I called it to his attention.

Most educated people…particularly when the words are being written rather than spoken…would use the version I called the “preferred” version.

How about bored with/by/of?

I hate seeing "bored of", but it's becoming more prevalent.

You've negated your argument from the outset, Frank. A much preferred version or even a preferred version or even a little bit better version all point to register differences.

At your recent dinner meeting/party/soiree [register differences] with Kicky, Lola, Bernie, ..., I'm certain that you were not using the highest register available for English. Had you done so, you would have all sounded like idiots, if not to yourselves, at least to those around you. Agreed?

So register obviously is vitally important in determining word choice/grammatical structure.
