Your examples using "rational" , "generous", "hard-working", "peace-loving" or "monogamous" do not compare to "spiritual" because unlike "spiritual" they do not contain root words that are linked to women, Jews, black people, Muslims or gay people respectively. If you look up "women, Jews, black people, Muslims or gays" the dictionary does not mention "ir/rational, un/generous, lazy/ hard-working, violent /peace-loving, promiscuous/ monogamous"
Nope - you are making a bit of a category error here.
You are quite correct that the dictionary definitions of women, Jews, black people, Muslims or gays does not include ir/rational, un/generous, lazy/ hard-working, violent /peace-loving, promiscuous/ monogamous.
But the comparator to women, Jews, black people, Muslims or gays in Sriram's statement is atheists, hence:
... even atheists can get salvationAnd on devotion, selflessness and wisdom which he sees as spiritual:
... even atheists could be spiritual (by which Sriram indicated he meant devotion, selflessness and wisdom)As far as I'm aware the dictionary definition of atheist is someone who does not believe in god or gods - no dictionary definition of atheist that I know of mentions saved/not saved; devoted/not devoted; selfish/selfless; foolish/wise; spiritual/not spiritual.
Perhaps you know of another dictionary definition of atheist that does mention those terms, but if not your point about dictionary definitions of women, Jews, black people, Muslims or gays is entirely irrelevant.
However the broader point about lazy negative stereotyping of groups of people remains valid and is just as valid for atheists as for women, Jews, black people, Muslims or gays (albeit the nature of the negative stereotype is different in each case), hence why my comparisons were completely valid and relevant.
