If anything, I would say fur gets a disproportionately high amount of attention from animal rights activists, relative to the total number of animals affected. According to Animal Charity Evaluators, an effective altruism group that focuses on animal welfare [0]:
> Of domesticated land animals used and killed by humans in the United States, over 99.6% are farmed land animals, about 0.2% are animals used in laboratories, 0.07% are used for clothing, and 0.03% are killed in companion animal shelters.
I am assuming they are grouping animals farmed for fur in the ‘raised for clothing’ category.
