Let's talk skilsaw/ portable circular saw issues

get a wood table, invert the saw through the wood just like its in the pic (that shoe would become the table) and make yourself a table saw. Run the fence parallel to blade. When your 'shoe' is not parallel, what do your cuts look like off a fence? seems the kerf would just be wider than the blade the amount of angle its off parallel, but youd still get a straight cut?
