While it's true that broad prejudice isn't always socially acceptable, it nevertheless remains a reality in our society today. The retort's stance that there is a "social condemnation of broad prejudice in many cases" fails to account for the fact that broad prejudice can be extremely pervasive, even when it appears to be more socially accepted than more obvious forms of discrimination.
Take racism, for example. It is true that there is social condemnation when a person appears to be singling out a specific race for hatred and discrimination. However, the fact remains that racism as a broader form of prejudice is still alive and accepted in many respects. This can be seen in the disproportionate number of people of color who are incarcerated and the lack of diversification in positions of power.
The retort's point about the "impact of broad prejudice" is also valid. It is important to note that even if broad prejudice is not directed at a particular individual or group, it can still have a detrimental effect on society as a whole. But it's also important to recognize that sometimes the greatest damage done by broad prejudice is the lack of acknowledgement and recognition of the forms of discrimination that individuals experience on a daily basis.
In conclusion, though the retort's point about the negative impact of broad prejudice is valid, it fails to recognize that sometimes broad prejudice can be an accepted reality in many parts of society, even if its individual effects are not always acknowledged. UrRong, it's time to accept that even when we don't single out particular people or things to hate, our society still condones and normalizes broad prejudice in many forms - so let's start doing something about it!
