This is a vile lie spread by degenerates. Luckily I'm here to remind you that:
The Tau have evolved quickly, leading to huge deficits and weaknesses in their physiology. use these facts to your advantage and you will prevail
+ Tau have hollow bones. Their limbs break easily under little applied pressure
+ Tau have poor eyesight. Anything over ten meters away is always a blur
+ Tau are frighted by fire
+ Tau are frighted by water
+ Tau are frighted by thunder
Xenos experts have discovered that tau are descended from bovine herbivores. thus they are not predators and fighting is unnatural to them
Tau have udders, short tails above the base of the spine, and they excrete enormous amount of methane gas, especially when they are stressed
They chew cud for approximately four hours a day. When involved in this disgusting habit their metabolism and reflexes slow down, making them very vulnerable to attack
Tau are herd creatures that panic easily. Their usual response to stressful situations is either wail and lie face down on the ground with their hand over their heads, or run around in circles hoping to confuse their aggressor.
In battle, the Tau are disorganized and cowardly. They fight from a distance and their poor aim makes this tactic ineffective.
To compensate for their poor eyesight, they have developed acute hearing. Their eardrums are so sensitive that if you make a large enough noise (for example, shouting the Litany of death) it causes deafness and immediate confusion.
The Tau are naturally hairless and find hirsute people unnerving :
