I'm not arguing anything. I'm merely pointing out that terms get coined.
That's what an argument is...
The religious right is no more of a powerful movement on the right than the SDS represented a large segment of the Democratic party.
The SDS itself wasn't a "large segment" because it was never a segment at all - the SDS rather pointedly did not support the party of LBJ during Vietnam. This is a rather marked difference from the role played by Religious Right partisans in the GOP, so trying to draw an equivalence be
Now, what we might call the 'soft New Left' of the late '60s - the part which had left behind the increasingly radical and ineffective SDS and similar groups - was, in fact, a highly influential segment of the Democratic Party. And would have likely elected a President were it not for his untimely assassination.
Small committed groups can sway opinion.
And large committed groups can sway opinion even more effectively.
Which is what the Religious Right is - a large, committed group of evangelical Protestants working with and within the Republican Party. It's really quite difficult to take seriously anyone who denies the role of Christian conservatism in the last thirty years of GOP history.
It would be like claiming unions don't support Democratic candidates or that African American leadership overwhelmingly works with the Democrats.
Propaganda is a powerful tool. And it is easy to bandy terms around when discussing issues. Opinion is one thing, truth is another.
Are these Zen koans or something?
