It would only be weird if we did not live in a society. We as a society have decided it is wrong, for example, to not hire someone because they have a disability and it would be an inconvenience to accommodate their disability, or to pay them less to account for the extra inconvenience, or to charge people with disabilities more for services (such as a plane ticket) because of those extra costs or inconveniences. We as a society have made similar decisions about treatment of people based on their ethnicity, gender, and many more criteria, including family status.
