That's ridiculous.
Let the opponents of the Resistance know that I know plenty of fellow Resistance supporters who are long-term supporters of the SSPX.
I have attended their chapels since 2000, but it's not like I was snubbing them before that. We attended an independent chapel 10 minutes from our house instead. It's not like we were going to the Novus Ordo or the Indult.
And 3.5 of those 13 years of attendance were at Winona, MN as a seminarian! Yes, I was willing to donate my whole life to the SSPX. And I've fervently supported them since then. So I think my opinion should carry some weight.
The first time I heard of the SSPX, it was my mother getting upset about how the media was treating Abp. Lefebvre in 1988. She was convinced that he was saving the Church. I was only a boy at the time, so that was basically my opinion as well.
So although we weren't traveling the 75 minutes to the nearest SSPX chapel, we were SSPX supporters as early as 1988.
According to my handy calculator, that was 25 years ago. Hardly a "blow-in".
