As someone with hypothyroidism I have been instructed by doctors to avoid fluoride ingestion. Topical dental use is what benefits your teeth anyway, not swallowing it.  
Fluoride was used to treat hyperthyroidism up until the 1950s, prior to the development of other thyroid-suppressing medications. Fluoride is effective as a thyroid suppressor at doses of 0.9-4.2 mg per day for hyperthyroidism. Most adults in fluoridated communities are ingesting between 1.6 and 6.6 mg of fluoride per day from water.
All other arguments aside- 
You really believe those of us with medical issues with fluoride ingestion should have to spend thousands on removing drugs that are bad for us from the public water sources we should have a human right to be able to drink? It must be nice that this issue affects your health so little that it's a joke to you. I suggest reading medical research.
