all of those existed before christianity (besides the crusades) and in fact christianity is against the opression of women and incest and helped end those practices
colonialism was never done in the name of christianity but rather in the name of money/power (often under the guise of being in the name of christianity) and most christians now oppose it
now admittedly a lot of churches still oppress lgbbq people, im against this personally but others will disagree
now islam was founded by a guy who wanted to opress women and do incest but couldnt because of the laws of his pagan faith so he decided to say that God had updated the scriptures which he had never read and changed it so he could do all that
