Question: What is a non-religious reason for avoiding dairy?
About the article "Dairy product", section "Avoidance of Dairy Products".

Candidate passages:
Some groups avoid dairy products for non-health related reasons:
Religious - Some religions restrict or do not allow for the consumption of dairy products.
For example, some scholars of Jainism advocate not consuming any dairy products because dairy is perceived to involve violence against cows.
Strict Judaism requires that meat and dairy products not be served at the same meal, served or cooked in the same utensils, or stored together, as prescribed in .
Ethical - Veganism is the avoidance of all animal products, including dairy products, most often due to the ethics regarding how dairy products are produced.
The ethical reasons for avoiding dairy include how dairy is produced, how the animals are handled, and the environmental effect of dairy production.
 and allergies.
Those allergic to dairy foods may find items labeled as "pareve" to be dairy-free, though this is not always the case.
"Kashrut" has procedures by which equipment can be cleaned of its previous non-kosher use, but that might be inadequate for those with allergies, vegetarians, or adherents to other religious statutes.
For example, dairy manufacturing equipment can be cleaned well enough that the rabbis grant "pareve" status to products manufactured with it.
Nevertheless, someone with a strong allergic sensitivity to dairy products might still react to the dairy residue, and that is why some products that are legitimately pareve carry "milk" warnings. 
Dairy Art Centre is a non-profit art institution in Bloomsbury, London. 
Some processes convert a meat or dairy product into a "pareve" (neither meat nor dairy) one.
For example, rennet is sometimes made from stomach linings, yet is acceptable for making kosher cheese, but such cheeses might not be acceptable to some vegetarians, who would eat only cheese made from a vegetarian rennet.
The same applies to kosher gelatin, an animal product, supposedly derived from kosher animal sources.
Other gelatin-like products from non-animal sources such as agar agar and carageenan are "pareve" by nature.
"Fish gelatin" is derived from fish and is therefore (like all kosher fish products) "pareve".
Eggs are also considered "pareve" despite being an animal product.

Women's rights activities.2005 municipal elections.
Al-Fassi was active in organising would-be women candidates for the 2005 municipal elections.
Election organisers did not allow women to participate, citing practical reasons.
Al-Fassi felt that authorities giving a practical reason for non-participation of women rather than a religious reason constituted a success for women's campaigning, since arguing against practical objections is easier than arguing against religious objections.
