List the three most persuasive reasons Houston gave in opposition of succession?

Sam Houston opposed secession primarily because he believed it would lead to civil war, which would be devastating for Texas and the nation. He argued that Texas would be better off within the Union, enjoying economic stability and protection. Additionally, Houston was concerned about the implications of slavery and the moral and social ramifications of leaving the Union, believing that secession would only exacerbate existing tensions. Finally, he felt that the rights of Texans could be better secured through cooperation with the federal government rather than through isolation.
