A classification of rational surfaces with effective $K$
Sorry, you are absolutely right about the first mistake, my proof is wrong. Anyway, just for the sake of truth, I didn't write that $-K_{X'}$ is ample; but it's not very important |

Irreducible divisors containing an arbitrary closed set
Thanks quim (and Simone) for the proof. I choosed Olivier's as best answer, but your answer was very useful to understand that the answer is much closer to Bertini than I expected. I also believe that your (*) should be always true. Maybe, in the case $V_i$ is contained in the singular locus, you can blow-up $V_i$, take an exceptional divisor $E_i$ mapping surjectivly on $V_i$, and take something like an horizontal section of the morphism $E_i \to V_i$. |

KLT singularities are quotient in codimension 2
Yes, I'm considering normal singularities. Would you be so kind to explain me how the result follows from the proposition in Kollar-Mori? Probably it's tivial, but I'm missing something. Thanks a lot! |
