I accidently posted this on another Bp. Tissier thread.
Just my opinion, but I think that Fr. Chazal gives a fair and balanced view of Bp. Tissier. He says good things about Bp. Tissier, but the fact is, is that Bp. Tissier was against the Resistance, and when Fr. Chazal went to him to express his concerns about the new direction of the SSPX, Bp. Tissier told him to "just be quiet!"
Fr. Chazal gives a reminder that Bp. Tissier wrote the best biography of the Archbishop that we have today. I've read it; it's excellent. But the truth is, Bp. Tissier didn't speak up about the SSPX new direction of seeking reconciliation with Rome.
Meg is spot on, Fr Chazal had a very balanced view of Bishop Tissier. If you say +Tissier didn't defend Archbishop Lefebvre by being silent about all the SSPX is doing contrary to what Archbishop Lefebvre did, it would not be criticizing him, it is merely stating a fact.
