Are Online Short Sessions Rude?

[girlsCanPlay2]

So according to some Site regulars, short sessions are rude. Do you agree and if so please let me know why I should care.

I often play short sessions due to various reasons:
1) I have a short attention span.
2) I dont like my position.
3) I dont like my table image.
4) I dont like a player at the table.
5) I have won alot of money and feel it will not continue due to various reasons, and decide to leave.

I would argue that I should not care, since poker is not about making friends or proper etiquette, it is about making money. The arguement that no one will play with you or you risk unpleasant interactions, dont hold up online.

What do you think?
