"Why are libertarians the only group held to a pure ideological standard?"

Because they keep espousing positions that have proven to be terrible ideas. They forget about history, and why things like government regulations came about.

I'm not sure libertarians are not opposed to regulation, they just require regulations to have a rational basis, and be restricted in scope. For example, not allowing murder is certainly a regulation, and I'm pretty sure libertarians generally are ok with that regulation.

Not all but some libertarians are arguably more familiar with history, because they understand the degree to which regulation historically has been twisted (generally: to screw over the poor), wheras their detractors have been sold the line that exists to defend the status quo on any given regulation.
