but vs however

i think that if the word however can begin a sentence, so can the word but.
especially if you're making a much stronger point.
however sounds so complacent. to the point of wussy. very indecisive. "however, it may not be that way..."
but 'but'. now there's a word with meaning. "you say this, BUT i say this". very crude and to the point.
from here on in, i am using but to make my stance in papers.
my profs will be angry but i think it's a worthy cause.
