No. This is not true in all cases. Most of the main stream amps for example use protective cutoff's at below rated impedance's. RF amps for example put out the same, if not less @ half ohm compared to 1 ohm.Dropping an amp to 1/2 ohm doubles the output current (up until the amp just can't put out more at least) and makes everything less efficient so the power supply in turn draws more current, often times inducing more voltage drop which calls for MORE current to maintain the same output level - again, turning into a cycle if it continues until something fails
From sundown himself, so in other words unless you have the power to back up half ohm you shouldn't do it.
