Agreed. It had more to do with the fact that the British were categorically opposed to Germany gaining enough power to contest their colonial projects and thus not allying with them (again not out of any anti-fascist sentiment, just purely out of self-interest) and political America being more closely allied with British political interests (because they speak the same language so it is easier to do business). If IBM or any of the major capitalist firms at the time had had their way, we would have allied with Germany immediately.
