Because ultimately the problem with cars is how many of them there are, not what kind of engine they use. If there were only ever, say, 50,000 cars in the entire world we might not even notice the environmental costs. But Google tells me that there are over a billion.
Put another way, a diesel bus carrying 50 people is better for the environment than those 50 people each driving a separate EV car. Not because the bus has less engine emissions, but because it's a more efficient use of materials and energy.
That is not a distinction actually made by section 3. Oath breakers are disqualified, not rebels per se.
There are probably good arguments why qualification for a federal office isn’t properly decided by a state judge or official.
State elections officials already do that for things like age, residency requirements, etc. It's part of federalism that the state governments administer federal elections.
all citizens are legally entitled to the same rights
It's worth pointing out that, in general and throughout history, citizenship is something that separates the privileged from the unprivileged. The in-group from the outsider. The masters and the slaves.
Touting the rights of citizens, therefore, does not necessarily rebut the parent comment's criticism.
Congress should pass a resolution removing Trump's disqualification.
That would satisfy the 14th amendment without setting a nasty political precedent while at the same time serving as an official recognition that Trump committed acts that triggered the 14th amendment.
Congress can only remove the disqualification, they can't impose it.
It's a problem that the amendment doesn't tell us how it's supposed to work, but the fact that other disqualifying factors (age, residency, etc.) are determined by the states suggests that the states can determine disqualification on the insurrection factor too, and through the same procedural mechanisms.
On the contrary, the more unpopular the speech, the higher the bar.
