oomis I feel that you’re comment is not realistic. It is not one person who will stigmatize such a child but the community as a whole. Divorce and death are common and natural situations where a child might lose a parent. There are thousands of such cases within the frum community world wide and even they come with at least a minimal amount of stigma. But children of extra-marital pregnancy by anonymous fathers would understand the events surrounding their conception to be entirely abnormal and become stigmatized on their own. Especially in a family oriented community like ours.
And is fulfilling biological urges a valid reason for anything? If men would fulfill their biological urges, Father’s Day would by quite confusing. As it is for other races. Is that acceptable?
