They always try to be obtuse to hide what they are doing. If there is a limitation on total taxes for old and disabled, and you reduce that limitation, aren’t you raising the taxation on them? As thackney notes in 8, it is to give the elderly and disabled the same as everyone else. They currently are getting a better deal than everyone else, so if you make it all the same, seems like it is hurting the old folks.
Amendment 5 is clearly about private roads, not public roads. And it is authorizing taxpayer money to do so.
Ammend 1 is not reducing the limit on total taxes. They are reducing the limit on exemptions taken off the their total taxes. This is allowing the same ADDITONAL $10,000 exemption to be added to the elderly and disabled, as well as the homestead.
Ammend 5 authorizes no taxpayer money, only enlarging the size of the county from 5,000 to 7,500 population. This already is permitted in counties under 5,000 people. That is the only change, increase the population limit, provided the county is paid for the work.
You really should go read that link.
