LOL!
None of my ancestors fought in Urban II's People's Crusade, none ever occupied Outremer, none fought Cathars, none sailed with Henry St. Clair and Antonio Zeno across the Atlantic, and to the best of my knowledge, none were on board the Lunar landing module with Neil Armstrong...but I can talk about all those things with a great deal of authority as well.
Perhaps you can, (or can't in some opinions) but those of us who had ancestors who fought for the Confederacy have factual information that you won't find in history books.
Just for your information, Texas had several hispanic regiments that fought for the Confederacy, including Col. Benevides, who served with distinction.
